Speaking as someone who has done several career fairs (as an employer), they've almost always went better at more selective schools. That's just the truth. Keep in mind it doesn't have to be a hyper-selective school, and it certainly doesn't need to be Harvard.

Outside of that, school selectivity has been only a mediocre predictor for individual candidates. You shouldn't ignore it outright, but you shouldn't be entranced by it. We've had MIT candidates who couldn't really program and a guy whose school I don't even remember who killed it.
