Lockheed Martin interviews on four official stages. On defense roles, the clearance gate comes first.

Why this mattersLockheed Martin runs its hiring on IBM BrassRing behind a Radancy TalentBrew career site, and its own hiring page names four stages: Find Your Fit & Apply, Application Review, Let's Talk: Interviews, and Offer & Next Steps. The behavioral format is officially confirmed, interviewers use STAR, and the interviews may be virtual or in-person. What reorders everything on defense roles is the gate in front: US citizenship and the ability to obtain a security clearance are screened before you can start controlled work. This page walks each stage, separates what Lockheed states officially from what candidates commonly report, and breaks down how depth and the clearance requirement shift across Aeronautics, Missiles and Fire Control, Rotary and Mission Systems, and Space.

The quick answer

What is the Lockheed Martin interview process?

Lockheed Martin publishes four stages on its own hiring page: Find Your Fit & Apply, Application Review, Let's Talk: Interviews, and Offer & Next Steps. You apply through IBM BrassRing behind the lockheedmartinjobs.com Radancy TalentBrew site, a parser reads your resume, and a recruiter reviews it against the requisition. Candidates commonly report a recruiter or phone screen, then a hiring-manager interview and a panel or technical interview that may be virtual or in-person, with role-dependent assessments on some engineering roles. Lockheed officially confirms interviewers use the STAR format, so your behavioral answers are read against its three core values: Do What's Right, Respect Others, and Perform with Excellence. The part that reorders everything on defense roles is the eligibility gate: many positions require US citizenship and the ability to obtain a security clearance, screened before you can access controlled work, and Lockheed sponsors the clearance for a specific job rather than granting it. Candidates commonly report roughly 4 to 10 weeks to an offer, longer when a clearance investigation is involved, though an active, in-scope clearance or an interim granted in about 5 to 10 days moves much faster. Prepare segment-specific depth across Aeronautics, Missiles and Fire Control, Rotary and Mission Systems, and Space, rehearse STAR stories, and scan your resume against the exact Lockheed posting. .

Lockheed Martin's own hiring-process page confirms that its interviewers use the STAR format and that background checks and security clearances can take time, and vary by role. For candidates, that means behavioral STAR preparation and early clearance framing are what to lead with, not a scramble the week of the interview.

Start with the gate, because on defense roles it sits in front of everything else. US citizenship, the ability to obtain a US government security clearance, and ITAR and export-control eligibility are screened before you can access controlled technical data. The reason is regulatory, not preference: the work is export-controlled, so Lockheed applies the filter up front.

Distinguish cleared from clearable. Cleared means you hold an active clearance and can start on cleared work immediately, often at a pay premium; clearable means you are a US citizen able to obtain and maintain one. You cannot self-apply for a clearance: a cleared employer sponsors it for a specific job, and the federal government grants it. An active, in-scope clearance in your resume header is a top-weighted signal, so lead with it; if you are clearable, say so explicitly rather than leaving it to be asked. If you already hold a DoD-issued clearance, tell the recruiter, because it may be transferable to Lockheed Martin.

The tiers below are the levels a defense role can require. The deeper the tier, the longer the background investigation, and some roles add a polygraph on top.

Confidential
The lowest DoD clearance level, investigated at Tier 3. It is the least common requirement on Lockheed engineering roles, which more often start at Secret.
Secret
The most common baseline on Lockheed defense roles, investigated at Tier 3 with roughly a 7-year scope. A new investigation commonly runs about 1 to 6 months, and an interim Secret can be granted in roughly 5 to 10 days on a clean SF-86.
Top Secret
A deeper Tier 5 single-scope background investigation with roughly a 10-year scope, for more sensitive national-security programs. Expect a longer timeline than a Secret.
TS/SCI
Top Secret plus Sensitive Compartmented Information access, where SCI is granted by an agency and commonly takes about 6 to 18 months. Some roles add a counterintelligence or full-scope polygraph, mainly on Space and Special Programs work.

Adjudication timeline

Days for an interim, months for a full investigation.

On a clean SF-86, an interim Secret or Top Secret can be granted in roughly 5 to 10 days. A full new investigation commonly runs about 1 to 6 months for a Secret, and about 6 to 18 months for TS/SCI, where SCI is granted by an agency. Lockheed states background checks and security clearances can take time, and vary by role, so an active, in-scope clearance is the fastest path through onboarding.

The gate also moves by segment. Defense-heavy work in Missiles and Fire Control, Space, and the classified parts of Aeronautics and Rotary and Mission Systems commonly requires a clearance, while some commercial-adjacent or corporate roles do not. We say many positions require a clearance rather than a percentage, because Lockheed does not publish one.

Aeronautics
Often cleared

Programs like the F-35, F-22, and Skunk Works advanced development are largely classified, so many Aeronautics engineering positions require a clearance; some commercial-adjacent roles may not.

Missiles and Fire Control
Commonly cleared

Precision-strike and fire-control work such as PAC-3, THAAD, and ATACMS is defense-heavy, so many positions carry a clearance requirement.

Rotary and Mission Systems
Mixed to cleared

Sikorsky rotorcraft and mission-systems work spans commercial and defense; many defense, Aegis, and C4ISR positions require a clearance, while some commercial rotorcraft roles may not.

Space
Commonly cleared

Missile-defense, protected-communications, and classified space work make many Space positions clearance-required, some at Top Secret or TS/SCI.

Typical posting language (described, not quoted)

Lockheed defense postings typically carry an eligibility block near the requirements: they ask for US citizenship and the ability to obtain and maintain a US government security clearance at the level the program requires, and they note the role is subject to ITAR and US export-control law. Lockheed may sponsor the clearance for a hired candidate, since a clearance is granted by the federal government and must be requested for a specific job. We describe this requirement rather than quote one posting verbatim, because the exact wording varies by requisition and program.

Read the stages in order, and read the provenance label on each. Lockheed's four named stages, the BrassRing apply, and the STAR format are the firm, verified anchors. The recruiter screen, the round counts, the panel shape, and the timeline are consistent across candidate reports but are not published by Lockheed, so treat them as directional. The one constant across all four segments is the shape; the technical depth and the clearance requirement are what change.

    Find Your Fit & Apply through BrassRing

    Lockheed's careers front end lockheedmartinjobs.com is a Radancy TalentBrew site, and its Apply button hands off to IBM BrassRing at sjobs.brassring.com. It is not Workday and not Taleo. A BrassRing parser reads your resume, so format for a clean parse and put your clearance status and US-person eligibility in the header, where a recruiter and the parser both see them, not buried in a project bullet. Lockheed's own hiring page names this first step Find Your Fit & Apply.

    Application Review

    Lockheed's hiring page names Application Review as the second step: a recruiter and the requisition team review your application against the role. Lockheed's virtual scheduling assistant, named LEO, sends scheduling emails from @paradox.ai addresses, so treat a paradox.ai scheduling email as a legitimate Lockheed touch, and still verify any link against the official lockheedmartin.com domain.

    Recruiter or phone screen

    Candidates commonly report a recruiter phone or video screen before the main interviews, covering eligibility and the clearance requirement first, then role fit, location, and motivation. Lockheed does not name this as a separate official step, so treat it as directional. On defense roles this is where US citizenship and clearance eligibility get checked, so state your status plainly rather than leaving it to be asked.

    Let's Talk: Interviews

    Lockheed's hiring page names the interviews Let's Talk and says they may be virtual or in-person and that you'll speak with recruiters, hiring managers, and team members. It confirms interviewers use the STAR format. The panel size and the technical depth are community-reported: candidates describe a hiring-manager round plus a panel or technical interview, with role-dependent assessments on some engineering and software requisitions.

    Offer & Next Steps

    Lockheed's hiring page closes with Offer & Next Steps, which includes a role-specific background check. Its official prep line for the whole process is short: bring examples, be real, ask questions. A conditional offer is what triggers clearance processing on cleared roles, because a clearance must be requested for a specific job.

    Clearance processing and onboarding

    On defense roles, onboarding then runs through security-clearance processing. Lockheed states background checks and security clearances can take time, and vary by role, and it sponsors a clearance for a specific job rather than granting one, which the federal government does. An active, in-scope clearance shortens this materially, and an interim Secret or Top Secret can be granted in roughly 5 to 10 days on a clean SF-86, while a full new investigation runs longer.

    Stage 6 of 6

The recruiter screen, the interviews, and the STAR format look similar across Lockheed. The technical portion is where the four segments diverge, and the gap is wide. Match your preparation to the segment on the posting, and name only the programs and standards you can defend live.

Aeronautics
F-35 Lightning II, F-22 Raptor, F-16, and C-130 programs; low-observable and stealth design; Skunk Works advanced development; AS9100 quality; airframe, propulsion integration, and systems engineering.

Combat-aircraft and stealth depth.

Missiles and Fire Control
PAC-3, THAAD, and ATACMS; fire control and precision fires; EO/IR sensors and targeting; guidance, seekers, and hit-to-kill engagement.

Missile-defense and precision-strike depth.

Rotary and Mission Systems (Sikorsky)
Sikorsky Black Hawk and CH-53K rotorcraft; the Aegis Combat System; radar and sensors; C4ISR and mission-systems integration.

Rotorcraft and combat-systems depth.

Space
Orion, GPS III, Trident II D5, and Next Gen OPIR; satellites and payloads; hypersonics and missile defense; systems engineering and mission assurance.

Space systems and strategic-deterrence depth.

The shared layer, every segment

Across all four segments, expect the cross-cutting defense engineering vocabulary underneath the program-specific systems: ITAR and export control, model-based systems engineering (MBSE), MIL-STD and DoD standards, systems engineering and mission assurance, and your clearance. Name the program systems on top of that base, and only the ones you can defend live.

Lockheed Martin officially confirms its interviewers use the STAR format, which its hiring page calls a tool its interviewers use to learn as much as possible about your experience. Read your STAR answers against Lockheed's three core values, Do What's Right, Respect Others, and Perform with Excellence, without assuming any single question maps one to one to a specific value.

Full Spectrum Leadership, Lockheed's leadership-development model with its five imperatives, is the frame most relevant to leadership and senior or management-track roles. It is a leadership-development model, not a universal applicant scorecard, so prepare it where the role is a leadership one and do not force every answer into it. Candidate accounts describe a safety-first, integrity-under-ambiguity style consistent with the three values, which is a community read rather than an official mapping.

We keep the specific questions in the Lockheed Martin interview question bank rather than repeat them here, so this page can stay on the process and the gate.

The order matters. Fix your segment and clearance path before anything else, because the four segments share little program-specific preparation and the clearance requirement changes the header of your resume. Then drill the segment-specific depth, rehearse the STAR stories against the three core values, and tune the resume last so it reads clearly for a BrassRing parse and a defense screen.

  1. 01

    Fix your clearance path and segment first

    Decide which of the four segments you are targeting, Aeronautics, Missiles and Fire Control, Rotary and Mission Systems (Sikorsky), or Space, because depth and clearance posture shift across them. If you hold an active clearance, put it in your resume header as a top-weighted signal; if you are clearable, state it plainly (for example, US Citizen, clearance-eligible). Many defense positions require a clearance, so confirm the requirement on the exact posting before you prepare.

  2. 02

    Prepare segment-specific technical depth

    Match your depth to the segment. Aeronautics expects F-35, F-22, stealth, and Skunk Works; Missiles and Fire Control expects PAC-3, THAAD, and precision fires; Rotary and Mission Systems expects Sikorsky rotorcraft, Aegis, and C4ISR; Space expects Orion, GPS III, and Next Gen OPIR. Across all four, expect ITAR, MBSE, MIL-STD and DoD standards, and systems engineering. Name only the programs and standards you can defend live.

  3. 03

    Rehearse STAR stories against the three core values

    Lockheed officially confirms interviewers use the STAR format, so prepare eight to twelve STAR stories and read them against the three core values: Do What's Right, Respect Others, and Perform with Excellence. For leadership and senior roles, be ready for Full Spectrum Leadership themes as well. Lockheed's own prep line is short: bring examples, be real, ask questions.

What is the Lockheed Martin interview process like?

Lockheed's own hiring page names four stages: Find Your Fit & Apply, Application Review, Let's Talk: Interviews, and Offer & Next Steps. In practice candidates also report a recruiter or phone screen before the interviews, which may be virtual or in-person with recruiters, hiring managers, and team members and use the STAR format, plus a background and security-clearance step on defense roles. Applications go through IBM BrassRing behind the lockheedmartinjobs.com career site.

How many rounds of interviews does Lockheed Martin have?

Lockheed publishes four hiring stages but not a fixed round count. Candidates commonly report roughly 3 to 5 rounds after applying: a recruiter or phone screen, a hiring-manager interview, and a panel or technical interview, with more on senior and cleared roles. Treat the round count as directional, not official.

How long is the Lockheed Martin hiring process?

Candidates commonly report roughly 4 to 10 weeks for the interview loop, with the security-clearance requirement the dominant timeline variable. Lockheed states background checks and security clearances can take time, and vary by role, so a new clearance investigation can add months, while an active, in-scope clearance moves much faster.

Does Lockheed Martin use STAR interview questions?

Yes. Lockheed's own hiring page confirms interviewers use the STAR format, which it describes as a tool its interviewers use to learn as much as possible about your experience. Prepare eight to twelve STAR stories and read them against Lockheed's three core values: Do What's Right, Respect Others, and Perform with Excellence.

Do I need a security clearance to interview at Lockheed Martin?

Not always. Many defense positions require the ability to obtain and maintain a US government security clearance, and cleared work requires US citizenship, but some commercial-adjacent or corporate roles do not. You cannot self-apply for a clearance; Lockheed sponsors one for a specific job, and the federal government grants it. If you are a US citizen able to obtain one, state that you are clearance-eligible.

How do I know a Lockheed Martin recruiter email is real?

Lockheed's virtual scheduling assistant, named LEO, sends scheduling emails from @paradox.ai addresses, so a paradox.ai email can be a legitimate Lockheed scheduling touch. Still verify: confirm the recruiter and any links against the official lockheedmartin.com domain, and be cautious of requests for money or sensitive personal data, which Lockheed does not ask for during recruiting.

Does an active clearance speed up hiring at Lockheed Martin?

Yes. A candidate who already holds an active, in-scope clearance can start on cleared work sooner and skips most of the investigation wait. On a clean SF-86 an interim Secret or Top Secret can be granted in roughly 5 to 10 days, while a full new investigation runs longer, commonly about 1 to 6 months for a Secret and longer for Top Secret or TS/SCI.
