Depends what you mean by "something," I suppose. Pedigree and pathway, sure. Knowledge and real training? That's the issue being discussed here.
Pedigree and pathway would get her hired, but not make her successful. She got 5/5 ratings in her recent reviews.
This is a silly back and forth until you can point at the "something" she got from b-school aside from pathway and pedigree. Again, that's what's being discussed. It's certainly possible that the degree got her the job, yet her own natural intelligence, undergrad experience, or professional experience led to her success. And /not/ the b-school curriculum.
That said, she's now a successful analyst at Merrill, so she must have gotten something out of it.
