If you're a startup, and you (the founders) have any sense at all, you will screen out candidates from "top 10" schools. As a startup, you have absolutely no business competing with Google / Facebook / et al engineering talent. This isn't even approaching anything like moneyball, it's just common sense. The idea that where someone went to school makes two shits of a difference in job performance is ridiculous. Job performance in technology is mostly about a collection of other soft skills in addition to grades and technical ability (communication, willingness / ability to learn new technologies, ability to work in quickly adapting work environments, etc).
