Booz Allen Hamilton interview questions

Overall a good interview - all the people had my resume and cover letter printed out with topics they wanted to talk about and questions they had. They were surprised that I didn't have a referral from someone in the company because I didn't know anyone. I hope that doesn't hurt my chances of getting the job... The front desk personnel was a little...intense. Not sure if they were having a bad day or not, but I felt like I didn't belong there. Very professional overall, and the interview felt more like a conversation rather than an interview. OF NOTE: I do not know yet whether I got hired, but I am thinking positive.
