Pretty straightforward asked me moderate technical questions and some personality trait questions. It was a panel interview made up of current employees. I was able to ask them questions about how they liked their jobs. It wasn't a stuffy meeting type interview, the interviewers were pretty down to earth. All in all a good experience.

The interview process was somewhat long as it lasted around 2-3 hours long with multiple interviewers conducting round-robin interviews. The questions were straight-forward with some focused on career goals, functional expertise, and culture/fit. The Booz Allen Hamilton interviewers were polite and friendly, but seemed hurried.
