Lockheed Martin is the world's largest defense contractor. With programs spanning fighter jets, satellites, missile defense systems, and hypersonic research, it's the kind of place where the work genuinely has global consequences. That's not just marketing language - it shapes how the company hires, how people behave on the job, and what they look for in interviews.
If you're applying to Lockheed, expect a thorough, structured process. This isn't a startup hiring on gut feel. The company operates under strict government regulations, security requirements, and ethical standards. The behavioral interview isn't just a formality - it's how they screen for the values they take seriously.
Whether you're coming from academia, another defense contractor, or pivoting from a commercial industry role, this guide breaks down what the process looks like, what they're evaluating, and how to prepare.
How Lockheed Martin's Interview Process Works
Online application and resume screening - Apply through Lockheed's careers portal. Tailor your resume to the specific job requisition and highlight clearance status if you have one. Many roles at Lockheed require an active Secret or Top Secret clearance, and having one gives you a real advantage in speed of hire.
Recruiter phone screen - A talent acquisition rep will call to confirm your qualifications, ask about your clearance status, discuss compensation, and gauge your interest in the role and mission. Be ready to talk about why defense work appeals to you.
Technical interview - For engineering, software, and scientific roles, expect domain-specific questions. You might be asked about systems engineering principles, specific technical domains like avionics or propulsion, or how you've approached complex technical problems. Some roles include a take-home case study.
Behavioral interview - One or more structured rounds focused on past behavior. Lockheed uses competency-based interviewing, meaning each question maps to a defined competency: ethics, leadership, teamwork, innovation, and so on. Panels of two to four interviewers are common.
Security clearance process - If you don't hold an active clearance, you'll go through the government's investigation process (SF-86 form, background check, sometimes polygraph for certain programs). This can take weeks to months. Hiring can be conditional on clearance adjudication.
Offer and onboarding - Offers typically include relocation assistance for roles requiring specific location. Onboarding includes ethics training that Lockheed takes seriously from day one.
What Lockheed Martin Values in Candidates
Ethics and integrity - non-negotiable
Lockheed has one of the most formal ethics programs in corporate America. They have a full ethics organization, hotline, and mandatory training. In interviews, they'll probe directly for your ethical judgment. They want to know if you've faced a situation where doing the right thing was difficult, and whether you did it anyway. Candidates who brush past this or give textbook answers without substance don't do well.
Teamwork in complex organizations
Defense programs involve thousands of people across prime contractors, subcontractors, government customers, and supplier networks. Nothing happens alone. Lockheed wants people who can work in that kind of environment - coordinating across organizational boundaries, managing competing priorities, and keeping the mission front and center when bureaucracy or conflict gets in the way.
Technical excellence and rigor
You're building things for fighter pilots and satellite operators. Precision matters. They want people who sweat the details, follow process discipline, and know when something isn't right. That means being honest about the limits of your knowledge and flagging issues early rather than hoping they go away.
Innovation within constraints
Lockheed does cutting-edge work - stealth aircraft, directed energy weapons, next-generation space systems. But innovation here happens inside a regulatory and contractual framework. The best candidates show they can think creatively while respecting program constraints, cost, and schedule. "I pushed for a new approach but first made sure it fit within our CDR requirements" is the kind of story that resonates.
Leadership and initiative
You don't need to manage people to show leadership at Lockheed. They value people who identify problems, own solutions, and bring others along. Especially for experienced hires, they want to see that you've taken initiative - proposed changes, mentored junior engineers, led working groups, or driven process improvements - without being asked to.
Sample Lockheed Martin Interview Questions (With Tips)
"Tell me about a time you faced an ethical dilemma at work. What did you do?"
Tip: This is a core Lockheed question and they take it seriously. Don't give a generic answer about choosing honesty over shortcuts. Pick a specific situation where the right course of action wasn't obvious or where speaking up had real cost - career risk, friction with a manager, delays to a project. Walk through your reasoning and what you ultimately did. They want to see your values in action, not a recitation of company policy.
"Describe a situation where you had to collaborate with multiple teams or organizations with different priorities."
Tip: Think about a time when the teams involved had genuinely competing interests. How did you create alignment? Did you facilitate a meeting? Escalate a conflict? Find a creative solution that addressed both parties' core needs? Lockheed's matrixed structure means this is daily life there. Show you're comfortable in that environment.
"Give me an example of a time you identified a problem before it became a major issue."
Tip: Proactive risk identification is highly valued in defense programs. Describe the cues that tipped you off - a metric trending the wrong way, a schedule slip, a supplier concern. Then show how you surfaced it, who you told, and what happened as a result. Programs get in trouble when problems fester. Lockheed wants people who don't let that happen.
"Tell me about a time you had to adapt your communication style for a different audience."
Tip: Lockheed employees routinely brief government customers, program executives, and technical teams. The ability to translate between technical detail and high-level summary is genuinely important. Pick an example where you had to simplify complexity without losing accuracy - or where you had to add technical rigor for an audience that demanded it.
"Describe a time when you disagreed with your team's direction. How did you handle it?"
Tip: They're not looking for yes-people, but they also need people who can operate within authority structures. The ideal answer shows you raised your concern through appropriate channels, made your case clearly, and then either influenced the decision or committed to the direction once it was made. The key word is "committed" - they want people who can disagree and commit, not sulk.
"Can you give an example of when you had to learn something completely new to complete a project?"
Tip: Defense technology changes fast. Lockheed wants people who are self-directed learners. Describe the learning challenge specifically - what was the gap, how you approached filling it, how long it took, and how it affected the outcome. Bonus if you then taught what you learned to others.
How to Structure Your Responses
Use the STAR method for every behavioral question:
- Situation - Brief context. What was the project, company, or environment? Keep this under 20% of your answer.
- Task - What were you specifically responsible for?
- Action - This is the heart of your answer. What did YOU do? Be specific and sequential. Avoid saying "we" when you mean "I."
- Result - What happened? Quantify if you can: cost savings, schedule recovery, defect reduction, customer satisfaction. If the outcome was mixed, show what you learned.
Lockheed interviewers will often probe with follow-up questions: "Why did you take that approach?" or "What would you do differently?" Treat follow-ups as opportunities, not challenges. They show genuine interest.
Keep answers focused. Three to four minutes per question is usually right. Practice out loud - not just in your head.
Mistakes to Avoid
Downplaying the mission. Lockheed is mission-driven. People there genuinely believe they're protecting national security and serving military personnel. If your answers are purely transactional ("I wanted good benefits and career growth"), it'll show. Find the aspect of the work that genuinely interests you and be able to articulate it.
Glossing over ethics. If your ethical dilemma story ends with "...and everything worked out fine with no real cost," it probably isn't the right story. They want to see you navigating real tension, not describing a simple right-versus-wrong moment.
Vague answers about teamwork. "I'm a team player" is meaningless. Give a specific example with real friction - teams that disagreed, timelines that conflicted, resources that were scarce. Show how you operated in that reality.
Not knowing your clearance status. If you hold a clearance, know your level and when it was last adjudicated. If you don't, be straightforward about that and show you understand the process. Trying to obscure or inflate clearance status is a disqualifier.
Skipping questions about why defense. "Why Lockheed specifically?" is coming. Don't say "I applied everywhere." Know what programs Lockheed runs, which business area you're applying to (Aeronautics, Missiles and Fire Control, Rotary and Mission Systems, Space), and why that work appeals to you.
Lockheed-Specific Preparation Tips
Research the business area. Lockheed has five main business segments. Know which one you're interviewing for. Aeronautics (F-35, F-22) is different from Space (satellite systems, GPS) which is different from Missiles and Fire Control. Tailor your examples to the kind of work you'll be doing.
Understand the customer relationship. Most of Lockheed's revenue comes from government contracts - primarily the US Department of Defense. Understanding that your "customer" is often a government program office changes how you think about requirements, reporting, and accountability. Show awareness of this dynamic.
Prepare for clearance conversations. If you've never held a clearance, understand the SF-86 process, know that foreign contacts and financial history are part of the investigation, and be prepared to discuss your background honestly. Interviewers won't usually go deep into clearance details, but they'll ask about your willingness to go through the process.
Know Lockheed's ethics resources. They have an ethics hotline, an annual ethics awareness program, and a Chief Ethics Officer. Mentioning awareness of this framework - not in a sycophantic way but in a genuine "I researched how you handle this" way - can strengthen your answers on ethics questions.
Practice quantifying your impact. Government defense programs run on metrics: cost, schedule, and technical performance. If your past work was on defense programs, be ready to talk about these dimensions. If it wasn't, find equivalents in your domain and translate them.
Final Thoughts
Lockheed Martin is a demanding employer that takes its values seriously. The behavioral interview is designed to find people who operate with integrity, communicate honestly, and can thrive in complex, regulated environments. If you've done work you're proud of, if you've handled hard situations with integrity, and if you genuinely care about the mission - those are the stories they want to hear.
Preparation makes a real difference here. Practice your stories out loud, time yourself, and make sure each one clearly shows your individual contribution. The candidates who stand out are the ones who are specific, honest, and reflective.
