Pros
I decided to work for Booz Allen because of the chance to work with some interesting technologies and projects, including biometrics and systems requiring high security.
Cons
The company is a consulting firm and their employee model is one where an employee works on an "engagement" which is a contract that can have a varied duration. At the end of the contract, the employee is responsible for finding another engagement within the company and if they cannot do so within two weeks, they can be fired. Management has no responsibility. There are a lot of opportunities for work, BUT 99% of them require relocation, which is not an option for everyone. Frankly, they don't pay enough to make a relocation like that worthwhile, especially given the short term nature of most of the work. The company really does not invest in its employees. They say they will pay for training courses, but then the money is never available. Even if you do take training, you have to make up the hours in additional billable work. The 401K match only occurs once a year, not quarterly. The upshot is that if an employee leaves in the middle of the year, they can kiss any portion of the match good bye. I don't know any other company that does that. The company talks a good game about ethics and values, but I have seen senior management make decisions where they then require employees to lie to customers.
