I worked my way in to a Booz Allen from some contacts that I had made while I was in the Air Force. Once I got my foot in the door I had an initial phone interview with the Hiring Manager for the local area. This interview really only covered my resume and my personality. From there a more formal interview was set up at their local facility. This interview would be a series of 1:1 interviews (5-30 min interviews back-to-back). The first 1:1 was really just to familiarize me with the project they were hiring me for and to allow me to ask questions. The second interview was a personality assessment and a further review of my resume. The third, fourth, and fifth interviews were primarily to see which part of the organization I would fit the best. All-in-all, the interview process was short, but to be fair this was also an industry and a product that I had a decent history with.
