I was referred to the position from an employee referral. I was contacted by a Booz Allen recruiter about 3 weeks after applying for the position.

I was unable to have an in person interview due to logistics. It took place over the phone.

After reading several interview responses here on Glassdoor for Booz Allen, I got the impression that there was little technical questions. This was not my case. Two of the five interviews grilled me pretty thoroughly so be prepared to answer questions about technologies you have listed as skills.

The interviewers were all very easy going and the process was quite pleasant.

I was asked by each interviewer the difference between abstract classes and interfaces.
