I applied through an employee referral. I interviewed at Booz Allen Hamilton (McLean, VA) in Nov 2012
Interview
The interview process went very smoothly. I initially had a phone screen and then was scheduled for an interview with several other applicants. You aren't interviewed together, but you do get an opportunity to meet other applicants before your interviews. Take time to get to know them if you can - they may be your future colleagues. Each applicant was assigned a room and interviewers cycled in and out. Most of the interview questions I received were behavioral, but I also received one case question. Overall, the interviews were more of a conversation about my experience and how I could add value to the firm.
