I applied online. The process took 1 day. I interviewed at Booz Allen Hamilton (Washington, DC) in Apr 2015
Interview
The process was pretty straightforward. You arrive, meet with your recruiter then you go to a select area where you will be interviewed. Instead of being interviewed in a panel, you are interviewed in phases. Each phase last roughly 30 minutes. Each a series of questions about what you currently do and how you would fit in to the BAH life. They then go into skill based questions which you answer and move onto the next topic of situation questions. The process is great.
I applied online. The process took 1 week. I interviewed at Booz Allen Hamilton (Fort Meade, MD) in Aug 2011
Interview
I recieved several phone call interviews which asked me various questions on my clearance and salary expectations along with if I would like to work at the newly formed US Cyber Command. Although my back ground did not perfectly match the position I was going to fill BAH asured me that my military background and relative experience would be more than sufficient. I was slated for a video interview as I was living in Hawaii and the job was in Annapolis MD, but a former boss who had just been hired by BAH told the team that I was a good fit and I was hited with in a week of being contacted.

three 45 minute round interviews, senior associate,principal and partner, each were split within a 20-25 minute behavior/case study. Interviewers were very nice and presented interesting cases with some having different levels of difficulty.
