I applied through a recruiter. The process took 1 day. I interviewed at Booz Allen Hamilton (McLean, VA)
Interview
3 interviews about 20 minutes a piece with mid-level managers. They were mostly look for "fit" rather than quizzing you on knowledge. It was a low-stress, and well organized day. I think since that time they have switched to a more speed-dating format. I think it really depends on the position. More senior folks will have a longer interview process, but for junior consultants it's a pretty streamlined process.

Question 1
Describe a time that you had to solve a problem creatively.
I applied through a recruiter. The process took 2 weeks. I interviewed at Booz Allen Hamilton (Herndon, VA) in Mar 2015
Interview
Very organized and professional. Applicants were give a general overview of BAH and benefits, and then presented to their respective interviewers - usually three. At the end of the interview process, about 1-hr, the interviewers meet separately and score the interviewee. This information and the desire to hire were submitted back to the HR recruiters.

Two phone interviews with peers led to onsite 1x1 interviews with several stakeholders in escalating importance.
