Northrop Grumman interview questions

Was called in for an interview for on-campus interview with group manager, who asked about my background and experiences. Some behavioral questions about how I work in a team, difficulties, etc. Followed by a surprised phone interview from direct manager and co-manager. Asked about my resume and some conceptual technical. Asked me to see if I knew my material from courses and how I my approach to solving problems from my previous internships. Was contacted by HR a week afterwards saying I will be getting the job offer! Official written letter was emailed another week later after they did their marketing research.

I met with Northrop hiring managers at my school's career fair. I showed them some projects I brought and the recruiter gave me his email. Emailed him and applied online. 1-2 weeks later, I had two 1 on 1 interviews for two different positions: The first one was all behavioral and the second one was pretty much all technical. Behavior one for the first position was a very easy going conversation and the questions were basic teamwork/leadership stuff. Interviewer was very friendly and personable. The second interview was the more technical one and it was terrible. Was given a surprise 3D force analysis test thing and absolutely bombed. I just went in too fast and didn't think about how stuff would work. Also, the interviewer was snarky and gave rude comments during the interview. I was told I would be contacted in a week. A week went by and I was told I was still being considered. The weekend passed and then I was told I got the first position, which I wanted.
