Booz Allen Hamilton interview questions

After an employee referral, I received a call from a contracted screener. Following a pleasant conversation, I was told to expect a call from a BAH staffer to schedule an interview. I interviewed at the McLean office about two weeks later. One other applicant and I received an overview brief by a hiring manager, then went through four 1-on-1 interviews. They were relaxed and friendly in tone. Questions were a mix of factual and behavioral. I was told to expect a call by the end of the next week. That didn't happen. I attempted periodic contact with the hiring manager over the course of a month with no reply. Finally, I received a phone call from the hiring manager letting me know that BAH and I did not have a match at this time. My experience with the interviews at the McLean office was very positive, but the slipshod follow through by the hiring manager was rude, and made the overall experience a negative.
