Lockheed Martin Operations Engineer interview questions

I was flown out to the Fort Worth headquarters and interviewed with a hiring manager. Hotel, rental car, and airfare were all paid for, as well as per diem for food.

1st Interview-90min phone interview with supervisor. Quite thorough as they had previously been in the position being filled. 2nd Interview-30min followup "2nd opinion" phone interview with someone from a different department. 3rd Interview-In Person: Brought out to location for 4hr interview. 1hr for a tour of the facility, 1hr panel interview with supervisor and people from different departments (typical experience/STAR questions), 1hr lunch with the position's current counterpart, 30min with the rest of the position's counterparts, and 30min with the department head. Overall a very thorough and exacting interview process. Never heard back even months later after multiple followups.
