The process took 1 day. I interviewed at Northrop Grumman (Linthicum, MD) in Nov 2011
Interview
The interview was a basic behavioral interview. Asked questions about job experience in the related field and whether I was willing to travel around the world (even to not so likable places like Afghanistan). Overall I think the interview went well.
