Northrop Grumman Software Engineer interview questions

Four 1 hour interviews. I was asked basic and technical questions, also free lunch. The technical questions were in many cases very vague and they would not elaborate making it difficult to give them an answer they seemed to want. They would just keep repeating the question.

interview was easy, talked about the stuff on my resume and my interests. didn't hear back since my interests didn't match up with the interviewer's. interviewer was also a software engineer.
