I know this might be sacrilege but as a neophyte to the consulting world's nooks and crannies, I wanted to know why MBB is so highly regarded versus, say, Deloitte, PwC, Strategy&, Accenture, or any number of other "top" consulting firms. Sure, it looks like the salaries are slightly (though not always) higher at MBB but is that the sole reason? Is there something I'm not seeing or hearing? Is it advancement opportunities that aren't available at other firms? Although it seems to me that if MBB are hiring all the top people, the likelihood that you'll get into a senior role as a real smart cookie is lower than if you chose to go to one of the other firms and knocked it out of the park there.
My real question: is the love for MBB hype?
