I was invited to interview weekend at my top choice university. Although I'm an international, I took a very expensive flight (on my own expense) to get there. The interviews went really well, and the POI said that I'm a very good fit to his lab, during and after the interviews. Yet, I got the generic rejection letter from the automatic system. I'm actually insulted, I expected that after coming to the interviews I would at least get the rejection from a faculty member, and not just a mass email. Is it always like that? Don't you get something more personal after coming to an interview weekend?
