Northrop Grumman interview questions

I got to meet with 4 people who work in that department, including the boss. They were all very kind and made me feel welcome. Instead of grilling me the whole time (which I kind of expected) they spent a good deal of time explaining their company and processes. I really got a great vibe from them.

Took me to a room with a whiteboard. Interviewed me for 3 hours, asking only technical questions. My interviewer was cold the entire time, like I was a bother to him.
