Pros
Great people Great place for a younger person to learn (provided you get staffed on the right sort of assignment, which is becoming lower and lower odds)
Cons
Of all the top consulting firms, BCG is by far the most focused on short-term profit per partner at the expense of all else. During the decade I was at BCG, I saw WAY too many decisions that were very bad for clients and non-partner consulting staff that got made to enrich current partners. Very smart people can come up with rationalizations for their actions, but at the end of the day what I saw take place very regularly at BCG was dishonest. As someone who served in leadership roles, was active in the CDC, etc, I still feel very guilty for some of things I was involved in. Every large company has some "bad apples", but at BCG, the "bad apples" gain more and more power because they the ones who are least apt to demonstrate any restraint or remorse for focusing purely on short term profit. The individuals who I saw lie, cheat and steal the most are now in enormous positions of power. I regularly hire consultants now that I'm an industry exec, but I would never hire BCG unless/until the current regime turns over.
