Pros
The pros of Booz Allen are few and far in between. Depending on the project, you may be eligible for work from home or remote work options which is just about the only thing I can think of.
Cons
Many Cons: The technical talent is very low in the engineering and data science areas. Many "data scientists" do not know how to code, have 0 knowledge of machine learning and statistics, and are hired because they have any resemblance of engineering knowledge related to math. I can understand that they are hiring bodies to train them later but the quality of work suffers immensely because of it. The pay is not anywhere near the industry standard either... Don't let the rebranding facade fool you - turnover is very high and many are hired to the firm without any clear project in mind for them leading to a surplus of employees on the bench looking for work even after their employment begins. As a data scientist, the only tasks that I have been given to work on are purely software engineering, computer infrastructure (basically IT support), and administrative tasks. This is definitely not a one-off situation as many of those whom I have met with are suffering from the same situation.
