Lockheed Martin Software Developer interview questions

Initial phone screening confirming interest in position as well as salary expectations, then setup time for onsite technical interview. Security at the building is a bit extreme, you have to put your phone in a locker and sign in to walk 10 feet past the main desk to a generic room for the interview.

About a week after submitting my application through Lockheed Martin's career page, I received a phone call from the Manager for the SWE dev team. We talked for about 15-30 minutes about my background & security clearance (this could be seen as an initial phone screen). We set up a time for a technical interview with him and one of his SWE. The technical interview did not involve any actual coding but instead asked about my past projects, general behavioral questions, and a broad system design question to model the problem set of the specific team I had applied to (satellite communication). It lasted about 35 minutes and afterwards the manager answered any questions I had. A few days later I received an offer from the team Manager. The whole process took about 2 weeks & I spoke directly to the manager (never to HR). I received an offer from the manager after the technical phone interview (no on-site interview).
