Business school is another beast entirely, in my experience. I studied engineering at an Ivy League school and sure I didn't fit in with the main finance/consulting/billionaire's child crowd, but there was a sizeable minority of peers pursuing careers in academia, medicine, etc. that I bonded with.

In business school, the ratio of mainstream to sidestream was skewed so badly towards the mainstream that it was difficult to even keep my head above water amidst the torrent of "networkers" like you said.
