Northrop Grumman Manufacturing Engineer interview questions

The process was very straight forward. I had been contacted by NGC about possible work. I had a quick conversation with our group director. It was short and I was told that in the near future a position would be opening up soon. About 1.5 months later I was contacted and a phone interview was scheduled. The phone interview was about 20 minutes long. After which I was asked to come in for a formal in-person interview. The in-person interview was a panel interview with three managers which last 3 hours. This may seem long, but the interview was very relaxed and the panel was actually very nice and welcoming. The three hours went by very fast.
