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).

Two round interview, Initial interview was very getting to know you and the company to see if there is a fit, Second interview was very behavioural and CV based with some basic technical questions.
