The best aspect of the BCG Internship was the Passport Meal program. Interns are actively encouraged to dine with Partners and Principals throughout the summer. Although they are the highest level in our firm, these senior co-workers prioritize these breakfasts/lunches/dinners in order to candidly share their career paths, speak broadly and specifically about the firm, and genuinely get to know the intern class.
Unfortunately in consulting, one case is very different then the next. There was a wide variety of summer case experiences given the nature of clients, teams, and work so there is no "typical" summer. I think BCG makes every effort to eliminate more unfairly challenging summer experiences, but there is bound to be one or two and for those few interns the summer may not be as rewarding.
Advice to Potential Interns
If you want a consulting firm that places internal people development on the same scale as external client relations, then BCG is the firm for you.
