Can't they atleast hire one person that didn't luck out by being born in a rich/middle class american family to go to ivy league universities. What is such complicated product that Fog Creek makes that it needs graduates from top 10 universities? Serious question.
The answer, I think, is because they are in the unique position of being able to get away with it. In the normal course of events you'll do worse looking for candidates from Ivy League universities than from people who haven't gone to college because you're fishing in a pool that has already been thoroughly fished by your competitors. But Fog Creek frankly doesn't have very many competitors in this regard, at least not ones remotely in the same league. They seem to be so much better at hiring interns than almost anyone else (in the sense of having a strong brand name to attract attention in the first place, a rigorous selection process and generous offers to those selected) that they will probably be able to pick the cream of the crop no matter where they look, so they have no need to look further afield.
So I think it's a case where the number one player can get away with something the rest of us couldn't.
