I've had several interviews within Lockheed Martin. None of them were the same. It really depends on the team, and how they chose to conduct their interviews. For example, my first interview with Lockheed was really easy-going. I went in really relaxed, got the typical interview questions (e.g., why are you looking to leave your current company, what are your strengths/weaknesses, etc.). I was only interviewed by one person, who was the Deputy Program Manager at the time. It was a small project and team. The second interview I had a few years later was a larger program. I was again interviewed by one person, same types of questions. This time it was the team lead that interviewed me. The interviewer was really looking for a baseline level of competencies, some strengths and a willingness to try and learn new things. Without boring you with all the interviews I've been on since joining (programs come to an end, mobility within the company), I'll share with you the worst. It was a tag team interview. The team was very bright and the work was equally interesting. I had a phone screen first, and shared with them my knowledge and weaknesses. I was then invited to an in-person interview. Every question they asked had nothing to do with anything on my resume, and they were questions that could have been asked on the phone thereby avoiding a waste of everyone's time. So, it really just depends.
