I applied through a recruiter. The process took 4 weeks. I interviewed at Northrop Grumman (McLean, VA) in Jan 2015
Interview
Applied and was contacted by a recruiter within 3 days. 2 days later they asked me to come in for an interview. 2 weeks passed after before they let me know that an offer was not going to be extended. very easy process and they were very friendly and accessible.
Very relaxed, laid-back, and informal which made me very confident and comfortable. I talked with a recruiter in a conference room with the hiring manager on speaker phone off location. Everyone was very polite and just wanted to get to know me, what I do/did, and if I could be a good fit for the company.
