I applied online. The process took 3 months. I interviewed at Northrop Grumman (Beale AFB, CA) in Nov 2011
Interview
Interviewed with 4 managers/shift leads on one call.
Interview questions [1]
Question 1
Technical questions were out of no where. Very random to cover a wide area of knowledge. Not looking for all right answers, just to see if you know some or all of the areas needed
The process took 1 day. I interviewed at Northrop Grumman in Jun 2009
Interview
There was a very short turnaround time between my submission and the interview. I found out that my situation was not the norm. While the company is great, their HR is dysfunctional for some reason. Others hired before and after me had to pull teeth to get through the process after the interview. Long and short of it, keep on HR after the interview.
