Pros
Working for Booz is like driving a BMW. You love to drive the car while the warranty is active. Once the warranty ends, it turns out it is not the fine tuned machine it claims to be. I worked for Booz for 2 years and the pay and benefits were great, but once the contract ended, they don't really help you find another task.
Cons
Booz is not a consulting firm. You are hired to fill one seat in a specific contract. Once the contract ends, good luck finding a new task. They have "career managers" that suppose to help you find another position, but they are only concerned with their own job security. My advice if you are contemplating joining the firm, accept the job on Monday and start to look for a more stable job on Tuesday. If something else comes up, take it even if you incur a pay cut.
