I applied online. The process took 3 weeks. I interviewed at Northrop Grumman in May 2012
Interview
1 brief phone interview, mostly personal questions followed by in-person panel interview. No curveball questions. Relatively straight-forward. Why do you want to intern here? What would you like to gain? Things like that
I applied through college or university. The process took 1 week. I interviewed at Northrop Grumman (Auburn, AL) in Sep 2012
Interview
I went to the Auburn University Technical Job Fair and met with some recruiters from Northrop. I did a brief informal interview with 3 people, one person was a hiring manager, one was an HR representative, and the last was the actual location manager I would be working under. They were really nice and seemed fun. Also, they were energetic about getting someone to fill this position. I scheduled an interview that day to do a formal interview at their facility. I met with potential co-workers and got good understanding of their expectations and the type of work I would be dealing with. I really enjoyed their process. The only thing I did not like was that the HR person (not the person I interviewed with) took 3 weeks to read my email about my employment history she requested which delayed my start date.
