Space industry interviews: what employers ask and check, from application to offer (2026)

What happens between applying to a space job and getting an offer: the questions application forms ask, the checks open postings name (counted every day), how each major employer describes its own interviews, and how to prepare for every stage.

Most advice about interviews is generic. Space hiring is not. Before a rocket, satellite or defense space employer interviews anyone, its application form has usually asked where you stand on export control and citizenship, and before it hands you a badge it may run a background check, a drug test and, for a large share of roles, a security clearance investigation that can take months. None of that is about how well you answer "tell me about yourself", and all of it decides whether an offer happens.

So this guide starts from what employers actually write down. Every day our research on what space job applications ask reads every open role on SpaceJobs.Now ( 18,705 today, from the job boards of about 150 space employers, among them SpaceX, Blue Origin, Rocket Lab, NASA, JPL, Lockheed Martin and Northrop Grumman) and counts what each posting says happens before a start date, and the application forms of the roles whose employers publish their form, and what the forms ask before any human reads your resume. Then, for each large employer, we read what it says about its own interview process on its own careers pages.

The short version:

• Export-control wording (ITAR, EAR or "U.S. person") appeared in 57.1% of open space postings on 3 November 2026, and today 83.5% of application forms ask about citizenship or U.S. person status before anything else.
• A security clearance was named in 34.3% of postings on 3 November; today 15.5% want one that is already active, and 13.1% say you must be able to obtain one after the offer.
• Background checks are named in 14.9% of postings, and in 98.5% of Blue Origin's and 100.0% of L3Harris's. A drug test or screen is named in only 2.3%, most of them L3Harris postings ( 100.0% of its own).
• Polygraphs are rare (3.1% of postings), and concentrated in intelligence and national security work.
• Interviews themselves are barely described in postings: only 2.2% mention a technical interview or technical screen, 0.1% a presentation, and 0.3% a coding test. On 3 November, of the 7,810 postings that use the word "interview" at all, 6,004 use it only in the disability accommodation notice.
• Application forms ask about salary expectations on 25.8% of roles, your GPA on 27.7%, and whether you have applied or interviewed before on 45.4%.

The rest of the guide walks through the process in the order you meet it: the form, the screens, the interviews, the offer and the checks after the offer.

1. The space hiring process at a glance

Every employer runs its own process, but the stages repeat across the industry, and so does their order. The employers' own descriptions in section 6 differ mostly in how many interviews they run and how long they take, not in what the stages are.

Two things make space hiring different from most technology hiring. First, the hard screens come first: export control and clearance questions sit on the application form, so a mismatch ends an application before any interview. Second, the process does not end at the offer: for cleared roles, the most uncertain step, the government's investigation, starts after you have said yes. Sections 11 and 12 cover what that means in practice.

2. What application forms ask before anyone interviews you

Many space employers take applications through a hiring system that publishes each role's form (Greenhouse, Ashby, Lever, Workable or Teamtailor). For those roles we read the form itself when the role first appeared on the board. On 3 November 2026 that was 7,667 forms from 71 employers, and the median form had 17 fields: your contact details and resume first, then the employer's own questions.

The questions that appear most often are not about skills. They are screens. (Our research report What space job applications ask tracks these figures as forms open and close; the shares below are its reading today, the employer counts the 3 November one.)

Citizenship or U.S. person status ( 83.5% of forms). This is the export-control screen. Rocket engines, spacecraft and much of their software are controlled under the International Traffic in Arms Regulations (ITAR) or the Export Administration Regulations (EAR), so employers ask whether you are a U.S. citizen, a lawful permanent resident or a protected individual (together, a "U.S. person"), or whether they would need an export license to employ you. 49 of the 71 employers ask it on most of their forms. Our ITAR and security clearance guide explains the rules behind the question; the short practical point is that the answer is a fact about you, not something to finesse, and a wrong answer found later ends the job.

Security clearance ( 51.7%). Forms ask whether you hold an active clearance, at what level, and sometimes whether you have held one before or would be willing and able to obtain one. 13 employers ask it on most forms. Answer exactly: "active" means the clearance is current in the government's system, not that you held one years ago.

Applied or interviewed before ( 45.4%). Eight employers ask it on most forms, SpaceX on 99.5% of its 2,579 forms. It is not a trap. Hiring systems link a new application to an old one, and recruiters read the earlier notes. Say yes if it is true and, if there is room, say what changed since.

GPA ( 27.7%). Asked mostly by one employer: SpaceX asks for GPA on 79.2% of its forms, and on the same share asks for SAT, ACT or GRE scores. Other employers rarely ask for GPA on the form; in postings, GPA appears mostly in internship and new graduate roles (section 9).

Salary expectations ( 25.8%). 19 employers ask it on most forms. Section 13 covers how to answer it with the pay data the board publishes.

The table shows the employers with the most forms on the board and what each asks, as each one's own page on this site reports it. The full breakdown for every employer is on its How to apply page (for example how to apply to SpaceX or to Rocket Lab).

What this means for you: read the form before you write anything else. If a role's form asks for U.S. person status and you are not one, the role needs an export license, and most employers say on the form or in the posting whether they will seek one. Our page on space jobs open to non-U.S. citizens lists roles whose postings do not carry the restriction.

3. What postings say happens before a start date

Postings describe the checks far more often than the interviews. Every day our research on what space job applications ask reads every open posting's text for each step and check below; the counts are today's, and a posting that names several is counted once for each.

Who may apply at all is the research on U.S. citizenship and clearances: today 62.3% of the on-site postings read are limited to U.S. persons or citizens, and that research has every employer's and every kind of work's share. A few wordings were counted once, on the 18,507 postings open on 3 November 2026, and are not read every day: U.S. citizenship mentioned at all (63.7%), export-control wording such as ITAR, EAR or "U.S. person" (57.1%), U.S. citizenship stated as the requirement itself rather than "citizen or permanent resident" (16.0%), any security clearance (34.3%), "pre-employment" checks of any kind (12.0%) and E-Verify (4.5%).

Three readings of the table matter for preparation.

The interview is the part postings leave out. Only 418 postings ( 2.2%) mention a technical interview, screen or assessment, 21 a presentation and 55 a coding test. That does not mean those steps are rare: it means employers describe them elsewhere, on their careers pages and in the recruiter's first call. Section 6 collects what the employers themselves say.

Clearance language comes in three strengths. "Active" or "current" clearance ( 15.5% of postings today) means the employer wants someone who already holds one, usually because the work starts on a cleared program on day one. "Able to obtain" ( 13.1%) means the employer will sponsor the investigation after the offer, and you must be eligible: in practice a U.S. citizen with a history an investigator can verify. A bare mention (the rest of the 34.3% that named any clearance on 3 November 2026) is often the employer's general statement that some of its programs are classified. Among the highest levels postings name, Secret leads in 1,317 postings today, Top Secret in 1,405 and TS/SCI in 1,520 ( clearance levels). On 3 November 2026 only 78 postings mentioned an interim clearance, which lets some people start work while the full investigation finishes.

Citizenship is mentioned far more often than it is required. On 3 November 2026, 63.7% of postings mentioned U.S. citizenship, but most of them do so to define a U.S. person: "a U.S. citizen or national, U.S. permanent resident, refugee or asylee". Only 16.0% stated U.S. citizenship itself as the requirement ( each employer's share of postings for U.S. citizens alone today), and those are mostly roles that need a clearance, which only a citizen can hold.

Some checks are boilerplate at one employer and absent at another. A background check named in 14.9% of postings sounds uncommon until you see that Blue Origin and L3Harris name one in every posting (section 5). Read the employer's standard paragraph, usually at the end of the posting: it tells you what happens after an offer there, whatever the role. Read it closely, too. Blue Origin's names drug and alcohol testing only for drivers of commercial vehicles and for roles that need a Merchant Mariner credential, and Rocket Lab's background-check sentence applies to its New Zealand offices only; neither is counted here as a check for every hire.

4. The checks by kind of role

The share of postings naming each check differs by kind of work. The table reads the board's 13 kinds of work every day, from the research on who can apply and the steps and checks postings name.

What the table says, role by role (the title-word families counted on 3 November 2026 in brackets, where they sharpen the picture):

• Systems engineering is among the most cleared work. Today 48.1% of systems, integration and test postings name a clearance and 29.1% want one active (64.3% and 40.4% of postings titled systems engineer on 3 November). Systems engineers on national security space programs work across classified interfaces, so employers hire people who can be read in at once. If you are a systems engineer without a clearance, the "able to obtain" roles are the door in, and they are fewer.
• Program managers and IT and cybersecurity staff come next. 34.1% of programs and business postings name a clearance (53.4% of program and project management titles), and software and IT postings name a polygraph in 5.4% (9.2% of IT and cybersecurity titles): a polygraph is asked of people with access to the most sensitive programs. Our security clearance jobs page lists the open cleared roles.
• Technicians and production roles carry the physical checks. A quarter of technician titles (24.8% on 3 November) named physical requirements (lifting, standing, working in clean rooms or at heights), and today 22.0% of manufacturing and technician postings name a background check. Section 8 covers what technician interviews test.
• Mechanical and propulsion postings name background checks often ( 23.8% and 19.6% today). Much of that is employers' standard text, Blue Origin's above all, whose engineering openings are heavy in those two kinds.
• Interns and new graduates face the export-control screen as often as anyone (64.5% of intern and new graduate titles on 3 November), but clearances less (18.9%): many cleared programs do not take interns. Section 9 covers what is different for students.
• Business roles are least restricted. On 3 November finance, people, supply chain and sales titles stated U.S. citizenship itself as the requirement in only 7.2% of cases and a clearance in 24.3%; today 27.0% of supply chain and facilities postings are for U.S. citizens alone, though 73.0% carry an export-control or citizenship limit, which many employers put in every posting.

5. The checks by employer

The employer's own wording decides more than the role does. The table shows 20 of the employers with the most open postings and the share of their postings naming each check, read every day (every employer is in the research on who can apply and the checks postings name). Where a share is close to 100%, the wording is part of the employer's standard posting text, so it applies to every role there.

Five patterns stand out.

• SpaceX screens on export control, not citizenship. Every SpaceX posting carries its ITAR paragraph: the applicant "must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee ... or (iv) Asylee", and its non-intern postings add "or be eligible to obtain the required authorizations from the U.S. Department of State". Clearances are named in 7.6% of its postings.
• Blue Origin and L3Harris name a background check in every posting, and L3Harris a pre-employment drug test too ("L3Harris maintains a drug-free workplace and performs pre-employment substance abuse testing and background checks, where permitted by law"). Blue Origin's standard text reads "Background Check Required for all positions". Expect them after an offer there, whatever the role.
• The defense primes screen on clearance. Northrop Grumman names a clearance in every posting, and its standard text says "U.S. Citizenship is required for all positions with a government clearance and certain other restricted positions"; Lockheed Martin names a clearance in 76.6% of postings. Their postings state citizenship or a clearance rather than the ITAR paragraph.
• The Aerospace Corporation is among the most cleared employers on the board: 71.9% of its postings want an active clearance and 14.4% name a polygraph. It runs a federally funded research and development center for the U.S. Space Force, and much of its work is classified.
• KBR has one of the highest polygraph shares ( 25.7%) of any large employer: many of its postings ask for an active TS/SCI clearance with a counterintelligence polygraph and intelligence community experience.

A share of 0% means the employer's postings do not name the check, not that the employer never runs it. Many employers describe their background check and drug test policy only in the offer letter.

6. How the largest employers describe their own interviews

Postings say little about interviews, so we went to the employers' own careers pages and read what each says about its process. Some publish a detailed description; several of the best-known space companies publish nothing at all. Where an employer publishes nothing, we say so rather than repeat what anonymous reviews claim.

Lockheed Martin

Lockheed Martin publishes a hiring process page with four stages: find and apply, application review, interviews, and offer and next steps. On interviews it says: "Interviews may be virtual or in-person. You'll speak with recruiters, hiring managers, and team members." Its advice is short and practical: bring examples, be yourself, ask questions, and know the STAR format (situation, task, action, result). It links a downloadable interview guide and a separate guide for leadership roles.

After an offer, "If selected, you'll go through a role-specific background check," and the page warns that "Background checks and security clearances can take time, and vary by role." Its FAQ adds that the number and length of interviews depend on the role's urgency, the business area and the hiring manager's approach, so two Lockheed candidates can have very different processes. With 77.5% of its postings naming a clearance (section 5), the clearance step is the one most likely to stretch the timeline.

Northrop Grumman

Northrop Grumman describes its process across four careers pages. The first contact after applying is a recruiter phone screen, which it calls "a brief (usually 30-minute) informal interview". The next phase is interviews with team members, the hiring manager and team leadership, and "interviews are more technical" there. Offers arrive through its Workday offer portal.

Its interview preparation tips are the most specific any large employer publishes: answer "tell me about yourself" in one to two minutes, use the STAR method, "Have at least three questions prepared to ask the interviewers", dress business formal, and send a thank-you note. Its interviewing essentials page sets one firm rule worth knowing in 2026: "During the interview, AI is not allowed, and recording or transcribing interviews is strictly prohibited."

After the offer, its what to expect page says a member of the onboarding team "will contact you to initiate your background check, drug screening and verification of security clearance." That is worth noting next to the posting data: Northrop's postings almost never mention a drug test, but its own careers page says one comes after the offer.

Boeing

Boeing's application guide and its interview preparation guide describe an eight-step online application, a recruiter review, and then interviews where "you'll meet with an interview team or panel of two to four people", which "may also include a subject matter expert, a hiring leader or a customer." It says "You may participate in multiple interviews", and that some roles include "case studies, coding challenges, presentations and other skills demonstrations." Some positions require a standardized assessment, and Boeing tells you in advance when one does.

Questions focus on past experience ("Tell me about a time when..."), and the guide has its own section on answering with STAR. One instruction is easy to miss and matters across the industry: do not share work samples that contain proprietary or confidential information. Boeing's careers FAQ also covers clearances: they are determined and granted by the Defense Counterintelligence and Security Agency (DCSA), not being a U.S. citizen rules one out, and financial problems, significant foreign contacts and foreign property can delay one. For video interviews, its virtual interview tips say to test your setup early and to dress for the whole interview, not only what the camera shows.

RTX (Raytheon)

RTX describes its process on its recruitment fraud page, in a section that also tells candidates how to recognize fake offers: the real process has "multiple stages including initial phone screens, interviews, reference checks, and job offer extensions," and after an offer "you will undergo a background check tailored to the role." Its timeline "may vary depending on the specific role and department." The useful takeaway is the order: reference checks come before the offer at RTX, so prepare your references early.

Amazon (Amazon Leo, formerly Project Kuiper)

Amazon publishes no process specific to Amazon Leo, its satellite broadband business, so its general process applies. The how we hire pages describe online assessments for some roles, a phone screen, and the interview loop: "You'll likely meet with two to seven people," each interview "around 45 minutes to an hour", including a Bar Raiser, an interviewer from another team whose job is to keep the hiring standard high. After the loop the interviewers meet in a debrief, and "You can expect to hear from us within five business days." After the phone screen, Amazon says it does its best to get back within two business days.

For hardware roles, Amazon's university hardware page describes "two rounds of interviews for full-time roles" with three to four interviews of 45 to 60 minutes, covering topics such as embedded systems, analog and digital electronics, and debugging. Across all roles, "A significant portion of the conversation will focus on how you've demonstrated our Leadership Principles", Amazon's 16 published principles, and the hardware page recommends the STAR method. Amazon also says "We won't ask brain teasers." If you interview in person, arrive 15 minutes early with a government-issued photo ID.

Anduril

Anduril's early careers page lists three stages: a recruiter call, technical and behavioral interviews, and role-specific assessments that can include "live coding challenges, presentations, or in depth technical discussions." It describes the process as rigorous and says your recruiter will guide you through each step. Applications are reviewed on a rolling basis, and not every applicant gets an update. Anduril's forms ask about clearance on 93.5% of its roles (section 2).

The Aerospace Corporation

The Aerospace Corporation's careers FAQ says only that its People Acquisition team compares applications with each role's requirements and contacts people selected for an interview. What it does state clearly is the clearance rule: "All Aerospace employees working in organizations with technical responsibilities are required to apply for and maintain at least a Secret clearance. U.S. citizenship is required." That matches the posting data, where 96.9% of its postings name a clearance.

The companies that publish nothing

SpaceX, Blue Origin, Rocket Lab, Relativity Space, Firefly Aerospace, Axiom Space and L3Harris publish no description of their interview stages on their careers sites as of 3 November 2026. What they do publish is eligibility: SpaceX's ITAR paragraph, Blue Origin's export-control paragraph and standard background check, Rocket Lab's "U.S. citizen or U.S. person" requirement for internships, Axiom's rule that "All candidates must apply through our official careers site," and L3Harris's pre-employment testing statement. Blue Origin also publishes its internship timeline (section 9).

For these employers, the reliable sources on the process are the recruiter, who will usually describe the next steps on the first call, and the application form itself, which tells you what the employer screens for. Third-party interview reviews exist for all of them, but they are self-reported, unverified and often years old, so treat them as anecdotes, not as the employer's process.

7. Technical interviews for engineers

Across the employers that describe them, technical interviews for engineers take four forms, often combined in one loop:

1. Technical discussion of your own work. Every employer that describes its process asks about past projects in depth. Expect to be asked why you made each design decision, what failed and what you would change.
2. Problem solving on the spot. A design, analysis or debugging problem worked through with the interviewer. Amazon's hardware interviews name embedded systems, analog and digital electronics and debugging; Northrop says the team interviews "are more technical."
3. A presentation. Boeing and Anduril name presentations among their assessments, and 141 postings on the board ask for one. A presentation is usually about a project you led, followed by questions; ask the recruiter how long it should be and who will attend.
4. Coding. Boeing names coding challenges and Anduril live coding. Only 52 postings name a coding test or online assessment, but software roles at space companies are interviewed much like software roles anywhere.

The postings add a little more. 418 postings ( 2.2%) mention a technical interview, screen or assessment: 2.6% of mechanical, structures and thermal postings, 2.3% of software and IT and 3.6% of systems engineering (3.3%).

Preparing the presentation. The most common failure in a technical presentation at a space company is not the content but the material. Do not bring drawings, data, code or analyses from a current or former employer: Boeing tells candidates not to share proprietary or confidential work samples, and space hardware data is often export-controlled as well as proprietary. Build the presentation from public material (published papers, your own university projects, open-source work), or describe the problem and your approach without the controlled specifics. Interviewers at these employers are trained to notice, and a presentation that leaks a previous employer's data counts against you.

Preparing for the questions. Re-read every project on your resume and be ready to go two levels deeper than the bullet. For each, know the requirement it met, the analysis behind the key decision, a number that shows the result, and one thing that went wrong. If the posting names a tool or method (our resume guide counts which tools each kind of role names), expect a question about it.

Coding interviews. For software, GNC and flight software roles, practice data structures and algorithms in the language the posting names, and practice explaining your reasoning as you code. Interview preparation services that teach coding interviews and system design are listed under this guide and on our job search tools page; our page on space jobs for software engineers shows what those postings ask for.

8. Interviews for technicians and production roles

Technician hiring tests what you can do with your hands and what you can read on a drawing. Of the 2,130 technician, assembler, machinist, welder, inspector and mechanic postings on the board:

Only 28 postings mention a practical test in so many words, but almost half ask you to read drawings, and certifications such as IPC J-STD-001 soldering, AWS D17.1 welding or the FAA Airframe and Powerplant certificate are themselves practical tests you have already passed. Our certifications guide covers which ones technician postings name and what each takes.

Expect the interview to cover:

• Your hands-on history. What you built, assembled, wired, machined or tested, on what hardware, to which standard, and how your work was inspected.
• Drawings and procedures. With 45.7% of technician postings asking (3 November 2026) for blueprint or drawing reading, expect questions on a drawing, a callout or a work instruction, and on how you handle a nonconformance or a step that does not work as written.
• Safety and quality. How you handle hazardous materials, pressure systems, torque values, foreign object debris (FOD) and documentation. Space hardware is built to procedures, and interviewers listen for someone who follows them and stops when something is wrong.
• Schedule and physical demands. Shift work, overtime, standing, lifting and clean room gowning are named in the postings above; the interview is where you confirm you can work the schedule the role needs.

The checks after an offer weigh more for technicians than for most roles: 22.0% of manufacturing and technician postings name a background check today, and on 3 November 24.8% of technician titles named physical requirements. Our guide to becoming an aerospace technician covers the path into these roles, and the technician jobs page lists the open ones.

9. Interns and new graduates: GPA, transcripts and timing

Internship and new graduate hiring follows its own calendar and asks for things experienced hires never see. Of the 922 internship, co-op and new graduate postings on the board on 3 November 2026, 69.7% say you must be enrolled in or pursuing a degree, 23.5% mention GPA and 8.0% ask for a transcript. On application forms, SpaceX asks for GPA and SAT, ACT or GRE scores on 79.2% of its roles, interns and full-time alike.

Timing. The employers that publish dates recruit months ahead:

• Blue Origin publishes its internship windows: for spring, "Application opens June 1st | Interviews conducted in July"; for summer, "Application opens September 1st | Interviews conducted throughout the fall."
• NASA JPL advised in a 2021 article on its internships to apply no later than November or December for the following summer, with answers usually by April; check its students page for the current cycle. JPL lists "Favorable review of your background check, drug screen, and verification of employment" among its internship requirements.
• Amazon's university hardware hiring runs two rounds of interviews for full-time new graduate roles, with three to four interviews of 45 to 60 minutes.

What interviewers look for. JPL's internship mentors most often cite problem solving, communication and teamwork, and want specific examples in the resume and in the interview. For students, the projects are the experience: a student satellite, rocketry team, design competition or research project is what you will be asked about in depth. Prepare it like an engineer preparing a design review.

The export screen applies to interns too. On 3 November, 64.5% of internship and new graduate postings carried export-control wording, the same share as experienced roles, so the citizenship and U.S. person questions on the form apply to students as well. Clearances are named less (18.9%), because many cleared programs do not take interns.

Our space internships page lists the open internships and co-ops, and space jobs with no experience lists the entry-level roles open to new graduates.

10. Federal jobs: NASA and the USAJOBS process

NASA civil servant jobs are federal jobs, hired through USAJOBS under rules set by the Office of Personnel Management (OPM). The process is more formal than any company's, and more of it is written down.

The stages. USAJOBS describes them on its application process page: the agency reviews applications, refers the best qualified to the hiring official, the hiring official interviews ("There may be more than one interview round. For example, an applicant may have a phone interview and then an in-person interview."), selects, and makes a tentative offer. Then "Once this offer is accepted the agency will start the background investigation," and "The job offer is final when the agency successfully completes the background investigation and any additional security checks."

The timeline. OPM's hiring FAQ says you will usually hear from the agency "in about 15-30 days after the job opportunity announcement (JOA) closes." OPM's hiring roadmap sets an 80-day standard for the whole process, with the number of days for each step "a suggested timeframe": for example up to 15 days to review, interview, check references and select.

The structured interview. Federal interviews are usually structured. OPM's structured interview guide describes questions developed by subject matter experts from the job's competencies, where "All candidates are asked the same predetermined questions and in the same order" and "A panel of trained interviewers takes detailed notes." The questions ask for a situation or task, the action you took and the result, which is STAR by another name. Every candidate gets the same questions, so the way to stand out is the specificity of your examples.

Assessments and written interviews. NASA's how to apply page says applicants may be invited to complete a USA Hire assessment. For one 2026 hiring wave at Marshall Space Flight Center, NASA's application overview describes a written interview of three structured, job-related questions, required of all applicants, with each answer limited to 700 characters, followed by human resources and subject matter expert review. That document's advice applies to every federal application: "Use the STAR method," give specific real-world examples rather than "generalities or textbook answers," keep the resume to two pages ("Resumes longer than two pages will be rejected"), and attach every document the announcement asks for, because "Missing documents is a major cause of disqualification."

NASA contractors are different. Many people who work on NASA missions are employed by contractors (JPL is managed for NASA by Caltech, and many roles at NASA centers are filled by contractors such as KBR and Amentum) and are hired through those companies' own processes, described in sections 5 and 6, not through USAJOBS.

11. After the offer: security clearances

For the roles that name a security clearance (34.3% of postings on 3 November 2026), the offer starts a second process: the security clearance. Understanding it removes much of the anxiety around it.

Who starts it. A clearance is not something you apply for on your own. The Defense Counterintelligence and Security Agency explains on its applicant processing page that "The security clearance process begins when a company determines that an employee or candidate for employment requires a personnel security clearance." The company's Facility Security Officer then starts your questionnaire, the SF-86, in DCSA's eApp system (it replaced the older e-QIP), you complete and sign it, your fingerprints are submitted within 14 days, and the case goes to investigation and adjudication.

The interim clearance. DCSA's interim clearance page says interim eligibility can be granted on a favorable review of the SF-86, a favorable fingerprint check, proof of U.S. citizenship and a favorable local records review, and that it "will generally remain in effect until an investigation is completed." An interim lets some people start cleared work while the full investigation runs. Only 78 postings on the board (0.4%) mention one, so do not assume it; ask the recruiter.

How long it takes. DCSA's pages that we could open publish no current timeline, and employers say only that it varies: Lockheed Martin's words are "Background checks and security clearances can take time, and vary by role." A Top Secret or TS/SCI clearance rests on a broader investigation than a Secret one, so it generally takes longer. Plan your notice period and any relocation with the recruiter, who sees how long recent cases at the company have taken.

What helps and what delays it. Boeing's FAQ names financial problems, significant foreign contacts and foreign property as common causes of delay. The SF-86 asks for years of addresses, employment, education, foreign travel and contacts, and references who knew you, so gather that history before you need it: a complete, accurate form is the one part of the timeline you control. An honest disclosure of a problem is a far smaller risk than an omission found by the investigator.

Which level. Among postings that name a level, Secret appears in 2,384, Top Secret in 1,793 and TS/SCI in 1,756. Polygraphs are named in 609 postings: 174 name a counterintelligence (CI) polygraph and 34 a full-scope one. Our ITAR and security clearance guide explains the levels, and space jobs with a security clearance lists the open cleared roles.

12. After the offer: background checks, drug tests and export control

The other checks after an offer are faster but just as final.

Background checks. Employers that describe them call them role-specific: Lockheed Martin's is "a role-specific background check," RTX's "a background check tailored to the role," and Blue Origin's standard text says "Background Check Required for all positions: Blue's Standard Background Check," with a Defense Biometric Identification System (DBIDS) check for roles that need access to a military installation. Boeing says it "will verify the education and work experience listed" in your application, and RTX checks references before the offer. The practical rule: everything on your resume and form must be true and verifiable, including dates, titles and degrees.

Drug tests. Only 2.3% of postings name a drug test or screen, most of them L3Harris, whose standard text says it "maintains a drug-free workplace and performs pre-employment substance abuse testing and background checks, where permitted by law." But employers also describe drug screening outside their postings: Northrop Grumman's onboarding team initiates "your background check, drug screening and verification of security clearance," and JPL lists a drug screen among its internship requirements. Blue Origin names drug and alcohol testing for drivers of commercial vehicles and for roles needing a Merchant Mariner credential. Assume a drug screen is possible at any employer with defense or government work.

Export-control verification. If you answered the U.S. person question on the form, you will be asked to prove it, usually with the same documents used for employment eligibility. The ITAR definition, in 22 CFR 120.62, covers "a person who is a lawful permanent resident as defined by 8 U.S.C. 1101(a)(20) or who is a protected individual as defined by 8 U.S.C. 1324b(a)(3)," together with U.S. citizens. 827 postings (4.5%) also say the employer uses E-Verify, the federal check of employment eligibility.

13. Salary questions on forms and in interviews

About a quarter of application forms ( 25.8% today) ask for your salary expectations before an interview, and on 3 November 19 employers asked on most forms: among them ICEYE (99.0%), Ursa Major and Spire (100%), K2 Space (98.3%), Voyager (97.7%), AST SpaceMobile (94.3%) and Rocket Lab (82.4%). The recruiter screen usually asks again.

Three things make the answer easier than it used to be:

• Many postings state the range. Pay transparency laws in states such as California, Colorado and Washington require a range in the posting, and the board shows each posting's stated pay. Our space industry salaries guide explains what each kind of role pays, and the salary calculator gives the stated pay for a role and place.
• Answer with a range inside the posted one, anchored on what similar roles at that employer state, which each employer's pay page shows (for example SpaceX pay).
• The real negotiation comes at the offer. The form's answer opens the conversation; the offer is where base pay, sign-on bonus, relocation (offered in 12.1% of postings on 3 November, see jobs with relocation) and start date are settled. Guidance on negotiating an offer is linked from our job search tools page.

14. A preparation checklist for every stage

Before you apply

• Read the posting's standard paragraph at the end: export control, clearance, background check, drug test. It tells you what happens after an offer.
• Open the application form and read every question before you write your answers (each employer's How to apply page on this site lists them).
• Decide your answers to the hard screens: U.S. person status, clearance status, willingness to obtain one, prior applications.
• Tailor your resume to the posting's named tools and methods ( resume guide).

Before the recruiter screen

• Have a one to two minute answer to "tell me about yourself" (Northrop's guidance), focused on the role.
• Know your salary range and your earliest start date.
• Prepare to confirm your form answers: the recruiter checks them.

Before the technical interviews

• For every project on your resume: the requirement, the key decision, a number, and a failure.
• Prepare four to six STAR stories (Lockheed, Northrop, Boeing, Amazon and NASA all recommend the format) covering a technical problem, a disagreement, a mistake, a deadline and a time you led.
• If a presentation is asked, build it from public or personal material only, never a former employer's data.
• For software roles, practice coding aloud in the posting's language.
• Prepare at least three questions of your own (Northrop's guidance).
• Check the employer's rules: Northrop forbids AI, recording and transcription during interviews.

After the offer

• Ask whether the offer is contingent, on what, and how long the checks usually take.
• For cleared roles, gather your history for the SF-86 before the form arrives: addresses, employers, travel, foreign contacts, references.
• Keep your current job until the conditions are met, unless the recruiter confirms otherwise.

15. Frequently asked questions

How many interviews do space companies run? The employers that publish their process describe a recruiter screen and then one interview stage with several interviewers: Boeing's panels have two to four people, Amazon's loop two to seven, and Lockheed and Northrop name recruiters, hiring managers and team members. Counting the recruiter, expect to meet several people before an offer, and ask the recruiter how many interviews the role has.

Do SpaceX and Blue Origin publish their interview process? No. As of 3 November 2026 neither describes its interview stages on its careers site; both publish their export-control rules, and Blue Origin its internship dates and standard background check. The recruiter is the reliable source for the steps.

Can I get a space job without being a U.S. citizen? Many, yes: export-control wording usually asks for U.S. person status, which includes permanent residents, refugees and asylees, and on 3 November only 16.0% of postings state U.S. citizenship itself as the requirement. Roles that need a security clearance require citizenship. Our jobs open to non-U.S. citizens page lists roles without the restriction.

When does the security clearance process start? After an offer, when the employer determines the role needs a clearance and its Facility Security Officer starts your SF-86 in eApp. Some people start work on an interim clearance.

Do space companies drug test? Some say so in every posting (L3Harris), some describe it in onboarding (Northrop Grumman's drug screening, JPL's for interns), and some name it only for specific roles (Blue Origin for drivers and mariners). Assume it is possible at employers with defense or government work.

What is a Bar Raiser? At Amazon, including Amazon Leo, an interviewer from another team who joins the interview loop to keep the hiring standard consistent across the company.

Should I bring examples of my work? Yes for your own or public work; never for a current or former employer's proprietary or export-controlled material. Boeing tells candidates explicitly not to share proprietary or confidential work samples.

How long does federal hiring take? OPM's standard is 80 days end to end, and you should usually hear within 15 to 30 days after the announcement closes. The final offer waits for the background investigation.

What should I answer when a form asks my salary expectations? A range inside the posting's stated range, based on what similar roles at the employer state. The board's pay pages show those figures by employer and role.

16. How we measured

The postings. Every day the research run reads every open posting whose full text the board stores, as its employer published it, and matches each check with a pattern applied to the text (the posting's own words: "background check", "drug screen", "polygraph", "technical interview"; the research). The first count, on 3 November 2026, read all 18,507 open postings in the board's public job feed with the same patterns; the wordings it counted that the research does not read are marked with that date above. A posting naming a check several times counts once. Two employer paragraphs were read by hand and corrected for: Blue Origin's names drug and alcohol testing only for certain job profiles (commercial drivers and Merchant Mariner roles), and Rocket Lab's background-check sentence applies to its New Zealand offices only; neither counts as a check for every hire. "Citizenship itself required" counts a posting only where the sentence does not go on to accept permanent residents, refugees or asylees. Kinds of work are the board's own 13 (each posting's kind); the 3 November title-word families are named as such.

The forms. For roles whose employer's hiring system publishes the application form (Greenhouse, Ashby, Lever, Workable and Teamtailor), the board reads the form when the role first appears. The figures cover the 7,667 forms of 71 employers open on 3 November 2026, as each employer's How to apply page on this site reports them.

The employers' processes. We read each employer's own careers pages on 3 November 2026 and quote them; where an employer publishes nothing, we say so. We did not use interview review sites, forums or third-party guides, whose accounts are self-reported and unverified.

What the numbers do not show. A posting that does not name a check does not mean the employer skips it: many employers describe checks only in offer letters. Postings change hourly, and the figures on this page change with them: each opens the row of the research report it comes from. The research files behind this guide are listed on our methodology page.
