I got an interview with Northwestern, but I am pretty sure I won't be accepted. I expected to have an interview with my POI, but instead there was another faculty member from a different field who didn't seem to understand some nuances of my research (my area is quite specific), so just by the voice I could tell that she wasn't impressed and interested. It is little disappointing, because I really wanted to speak with my POI, but still hope to hear from other top schools
