Pros
Booz Allen is a highly respected organization in the contracting world. Their philosophy of strategic hiring vs. other companies who may not retain you at the end of a contract. There seems to be a flexible work schedule mentality if it is at all possible to meet client needs. The Firm definitely seems to care about its people and works to take care of them through various programs and benefits. There are many opportunities for employees to better themselves, their community and the Firm as well. Their retirement (ECAP) program appears to be good although you must be with the company for one year before you receive any of the contribution.
Cons
Times when you are looking for work...slow periods with busy work to do. Sometimes focus seems to be on new proposals rather than delivering well on what we've already won.
