You're the consultant. Being a consultant is not always glamorous and is not always fun. Each new assignment means a new company, new people who are wary of you, and an entire culture to learn in a very short time. For some people this is a challenge and a thrill. For others, it's chaos but it does have its advantages.
Consultants are hired for the ability to solve problems and candor is required.
All that aside, Booz's corporate culture according to Mike, has evolved to better emphasize balance, teamwork, and a good quality of life. They are more tolerant of people's quirks than they used to be, and want to prevent burnout. They are a client driven company so the consultants are subject to the whims of the client. If the hiring company is old and stodgy, you will need to be too. You'll still have to shave in the morning.
