The process took 5 days. I interviewed at SAIC in Aug 2008
Interview
Pretty standard interview process, I was interviewing for fresh out of school programmers position. The phone interview had some basic c/c++, web and db questions. Nothing too fancy.
I applied through a recruiter. The process took 1 week. I interviewed at SAIC (Arlington, VA) in Jun 2012
Interview
I was contacted by a recruiter about a day or two after posting my resume in their database. After I talked with her and applied for the position officially, it took the hiring manager less than an hour to decide that they wanted to bring me in for a personal interview. I met the hiring manager and the next day they came to make me an offer.
I dont think the interview was hard. Ive had three interviews with SAIC and they are all different. Not nearly as hard as interviewing with Booz Allen Hamilton
