Northrop Grumman Software Developer interview questions

Attended a career fair at my school, met with Human Resource representative at their booth. Had initial discussion regarding potential opportunies and locations. I submitted a resume at the booth. Received a call back with basic, initial phone screen. Scheduled on-site interview. Interview was with 2 program managers and a deputy engineer. Straight forward interview, basically going over my background and experience. They asked some basic questions and made a pitch of the project and work.

I was interviewed by 3 different teams for the potential project I would work on. The panel consisted of 3 people, usually the project manager, technical lead, and another engineer. They talked gave background on their projects and the role I would be taking on. They talked about the work environment and what to expect. I was then asked questions by all three members of the panel for around 1-2 hours each. The questions were both technical and to assess personality/working style.
