I went through an internal referral and connected with a recruiter for this position based in San Diego. The first step was a standard phone screen, followed by a panel interview on Teams. As a heads up, on one prior occasion, they scheduled an interview with me then cancelled it because the position was filled internally (a little bit frustrating, as they should have an internal job board and external to avoid confusion). Before the interview, they offer an optional information session that occurs weekly, or candidates can watch a prerecorded session. They also sent a copy of the STAR interview method, but it wasn't particularly helpful for my interview, as the panel didn't pose many behavioral questions.
The top of their range was $126,000 for an experienced position based in San Diego, one of the highest cost of living cities in the US. They were pretty inflexible on this, and the recruiter told me straight up that my salary requirements were "likely too high," which felt inappropriate, especially when you consider Booz Allen's CEO often receives an annual salary exceeding $14M. Further, in the time since my interview with them I've interviewed for positions with similar contractors for similar positions, with salary ranges starting at least $20k-$30k higher. The position in San Diego also didn't permit any telework for some reason, making the salary even lower in real terms. Again, I interviewed with contractors working at the same facility that offer telework and higher salaries, so it's clearly not solely a DOD policy decision. The bottom line is they don't pay enough for what they ask of their employees, and this should be rectified for them to remain competitive. I recommend going elsewhere for more money and a more flexible schedule.
