I strongly disagree. Most of my coworkers are not from "top colleges". Neither are most of the people I interview. Even for Google, it is tough getting interviewees who do very well. Given that, it'd be ludicrous to discard most interviewees out of the bat because they didn't come from a "top school". The interview questions and relevant job experience are the true hiring bar. Possession of a relevant degree, and the granting institution for said degree, is far down the list.
