Applied through on-campus recruiting and had a few employee referrals. Went in to the office for two back-to-back 30-minute interviews with senior managers. Mostly behavioral questions. They don't expect you to know everything about Lockheed's line of business, but they went to see that you are anxious to learn. They called me two days later and congratulated me and getting the job. About 8 business days later the offer paperwork came through.
