Northrop Grumman interview questions

No technical interview. Did ask some design/knowledge questions. They gave only one phone call interview and then I got an offer in a few days. Interviewer and recruiter were very friendly and seemed to genuinely enjoy working there.

2 rounds, 4 people panel tech interview for last round, company introduction, framework and tech used. resume project discussion, java fundamental questions, not too much difficult, comfort talk as a whole
