One thing to be aware of is that Booz Allen does a fair number of interviews before they are actually ready to hire. It took me 2 years of interviews to get hired. Mostly because the projects they were bidding on were repeatedly canceled. This was from 2008 to 2010 i.e. recession central so if you are trying to get a job don't get your hopes up too much unless the position is fully funded and they want you to start in two weeks. Out of all the interviews I did I started to know people pretty well by the end. My first interview I thought went really well. It was mostly chit chat type stuff about my resume with 4 people in a series of one on ones. Not stressfull at all. At the time I think I was the only person remotely qualified so they knew going in they wanted me. The second one was also not too bad again just talk about what I did based on what I put on my resume. The third was brutal they asked me to explain concepts from my graduate school days and had me doing mental gymnastics. It was also all over the phone not in person unlike the first two. I thought I had no chance of ever getting hired after that interview. It was by far one of the worst interview I ever did. At least from my perspective. Then I had the fourth and last interview. They called asked if I was still interested. I almost said no, because by that point I was tired of getting my hopes of finding a real job crushed, but I said I was interested. They said great. We will be in touch in the next few days with an offer. The so called interview took about 90 seconds. 1 or 2 day later they offered me $55,000 and I got hired. Best advice I have if Booz Allen interviews you twice. You will be getting hired one day. It just might take some time to find a contract that doesn't fall a part at the last second, so never give up if they interview you twice. Another tell that Booz Allen has if that if they really like you, you get a call within 24-48 hours of posting for a job. That means you are at the top of the list. Also never take a interview for granted. If it is econ type work brush up on your basic econ theory. If it is math work, then brush up on math. You will quite possibly be asked to explain some random theorem or concept. This probably only applies to people who are young and just out of school. I applied shortly after getting my masters in math.

The Booz Allen consultant interview process was pretty straightforward—started with a recruiter screen, then a couple of behavioral interviews, and a case-style or problem-solving conversation. Overall, it focused a lot on teamwork, communication, and how you think through challenges. It felt professional but conversational.
