BAH, no question as it will give you so much more ...If you are interested in cosulting as a long term career (i.e. you want to make partner fast), where and how you start is vital. Clearly, the higher in the foodchain the better (I mean MBBB). In the event you cannot make it with the big guys - assuming you have the right motivations/skills - there is a plethora of others consultancies that would be more than happy to give you that opportunity. You can even go "solo".If, instead, consulting for you is a way of fast tracking a career in industry, there is no better thing that having one of the big guys (MBBB) on your CV. And I have direct experience of that...So go BAH, you won't regret it
