Pros
Good firm brand recognition in the Washington, DC and San Diego, CA areas. Large company that you can take charge of your career and move around to different projects to diversify your portfolio of clients. Or you can have management place you on a project and stay there for years. Predominately Federal clients with a small but growing Commercial practice. The Booz Allen internal network is fairly supportive - just need to find the right people.
Cons
Leadership and project management is solely focused on supporting the clients first and not BAH employees. HR and Employee Relations are inconsistent in their feedback and handling of difficult employee / client HR issues. Expect zero assistance from the firm if the client is verbally abusive and harass BAH employees. If you are not billable to a project expect 1 month of "bench" time depending on your career level/salary could be more. If you need to change projects internally: the process is not streamlined or automated and very cumbersome/time-consuming on the employee. The majority of hiring managers are not responsive to internal requisition inquiries which makes the process even more frustrating. You really need a good network at BAH to internally realign. Minimal firm brand recognition outside of DC and San Diego.
