ckoga -- beyond contacting the Admissions Office and reading their report here (
https://www.stern.nyu.edu/portal-partner ... -reports-2), another way you can get more granular in your research is through creative searching on LinkedIn.
Do an advanced search, enter "Stern" as the School and enter (say) "Bain" as the Company (Current or Past). You'll need to do separate searches for "McKinsey" and "Boston Consulting Group"
You'll then see hundreds of Stern alumni with MBB experiences and by perusing their public profiles (or searching on languages they speak) you'll get a better sense of what you're looking for.
Hope that helps!
Cheers, Chris
