Booz Allen Hamilton interview questions

I passed my resume to someone in the company (the best way to get your resume noticed) and was called in for an interview. I interviewed with five people for a total of three hours. Afterwards, I was allowed to ask questions and was given a tour of the office.

I had been looking for a new job for about 3 months when I met up with a colleague I worked with at a previous employer. She has been at Booz Allen for about 2 years and encouraged me to submit my resume through her. Within 2 days of that submission, an HR rep emailed me asking for a 30 min phone conversation that week. In that conversation, she asked very basic questions, such as "Why Booz Allen?" and "Do you have a security clearance?" At the end of that conversation, she asked if I was available the following Friday to come to their McLean office for an in-person interview. When I showed up for the interview, there were about 20 other people in the room also competing for positions, but they were of varying ages and backgrounds, so I wasn't sure how many spots were available or what skill sets were in demand. I interviewed separately with 3 people from the functional area I would potentially be joining (Organization and Strategy), and they mostly asked questions related to my previous work experience. They posed a few simple potential client situations, and asked for strengths/weaknesses, but that was about it. I received a call about 5 days later saying they would like to offer me a position. About a week after I accepted their offer, I received another call from a different division within Booz Allen, saying they had received my resume and wanted to conduct a phone interview to determine if I may be a good match. When I told him that I'd already received and accepted an offer with Booz Allen, he was very surprised. It seems the HR people don't really communicate between divisions. After working here for 2 years, I find that this miscommunication is actually quite common in all areas, not just HR.
