Not just for dev. I went to NIPS last year (and am in DS at startups in SF) and about 80% of the time as you introduce yourself the other person just stares at your affiliation on your tag. I went to a company (nameless) afterparty where the host DS literally stared at my tag for 2 seconds with a look of some serious disgust of how did I happen to get in without Google/FB/Apple/etc. or MIT/Stanford affiliation.

similar experience here, I'm actually glad that the schools don't coach their students to tone down the arrogance as it makes interviewing them a lot easier
