I just received some correspondence from a school I recently interviewed at. It was signed by all of the admissions directors, but one of them (the dean who interviewed me) wrote a little note on the side telling me how much he enjoyed meeting me and how he hoped I would keep in touch. Is this typical? 95% of me knows that this is probably a common courtesy and that all interviewees receive some kind of note, but 5% of me keeps hoping that this is a good sign of some sort. Has anyone else gotten anything else like this?
