Dunno if it was Harvard as a whole, but a couple of years ago I read a rapport that Harvard feeds roughly 66% of all their grads into Finance, Management Consulting, Big Law, and Tech - basically elite white-collar jobs - despite only around 25% of their student mass studying anything related to those fields.

I guess most Harvard grads go where the money is.

EDIT: But a bit more related to the OP, when I studied EE (undergrad) in a college with close ties to the oil and gas industry, we were all wined and dined by big oil for the last 2 years.

During one of those dinner events, hosted by a big service company, they told us to just sign our names and major on a form they passed around - if we did that, we'd get a job offer in the mail a week later. Some of the larger oil (production) companies guaranteed free housing for the first two years, and they'd cover 50% of the mortgage for 5 years if we decided to purchase a house. That was on top of a high starting salary w/annual bonuses.

Should be mentioned that this was during the height of a boom cycle.
