Northrop Grumman Software Engineer interview questions

I was first contacted by a recruiter. Then she briefly explained the job and its compensation then set up an interview for me. The interviewers first described the job; what is it about? what is a daily work cycle? Then they asked about my background; what had I done so far? what did I do in my previous/current jobs/research position? No technical questions were asked. Followed up by the recruiter, she said I did a good job in the interview and they would extend me an offer. No negotiation was done. The offer was given a few days after the interview.
