Pros
There are great training opportunities, both formal and informal. Booz Allen offers a lot of classes, has partnerships with various educational programs, and also has opportunities for individuals to present the lessons they've learned from their project to colleagues. The 360 yearly assessment process ensures that an employee's accomplishments and skills are evaluated by a number of peers, not just one manager, which helps to keep the assessments more objective and comprehensive. Booz Allen has a great reputation within the government consulting industry and are well respected in the DC metro area.
Kontras
Projects that are more geared towards staff augmentation of a government agency tend to try to keep employees on projects for a longer period of time, hampering an individual's ability to grow from new projects, industries, and experiences. The 360 assessment process is very time consuming and dependent on the skill and motivation of the third party assessor. Some might say Booz Allen is becoming more of a government contractor than a true management consulting firm, especially since Booz&Co has spun off to become its own entity. Compensation is lower than competitors.
