Pros
Great benefits. Good if you are seeking long term job and are not too worried about climbing the ladder. They have deep resources. It can be a good place to launch a career. As long as you are making they money they are happy. They have good infrastructure, pay you on time and pay expenses quickly. They have good people. They are listed as one of the top 100 places to work. They do hire good people and seem to realize, to an extent, that people are what make their company. In other words, people are their asset. If looking for a good stable job it might be the place for you.
Cons
Seems to be hard to make more money/break through to level 4. I have made them lots of money over the past year, but do not believe that I will see the return when my year is up. This does not really motivate me to try to get them more business. It is an extremely corporate environment. It can be difficult for those who do not fit the mold. At times it seems that they are more about getting the business then delivering. However, this is a balance that most consulting companies must walk. Although I am stable with my client, I do not feel stable with Booz. This makes me feel like I might want to jump ship.
