First interacted with Northrop Grumman at my university's career day. Simply talked to them about their business management opportunities, handed them my resume, and went on my way. I received an email about a week or so later asking me to sign up for an interview slot. I interviewed with them about three weeks after initial contact. There was just one behavioral interview and my interviewers were very nice and open to everything I had to say.

Northrop Grumman came to visit my college and I got details on how to apply then. I submitted my resume on their website and got an interview 2 weeks later. It was a 45 minute interview in person with 2 managers (not hiring managers, but actual program/project managers). I was asked 6 or 7 complex behavioral interview questions, then time was up. Nothing regarding my resume or skills were even touched upon. Almost every question asked for detailed descriptions of how I responded professionally in highly difficult situations and what the results were. They were friendly and warm people but the questions were intense to answer on the spot.
