Northrop Grumman interview questions

I applied on their website to several jobs and after a month I heard back from a recruiter who set up a 30 minute phone interview. The recruiter didn't have much technical knowledge so it was a very general interview to make sure I met their pre screening requirements. About a week later they set up an in person interview with a hiring manager. It was very relaxed and low pressure of which was surprising because similar contractors have been very difficult.
