Eeek, isn't it supposed to be funded?
My impression of the interview was a little bit different from some of your experiences. It seemed fast and maybe more like a vibe check, but I really loved how the professors answered my questions - it was clear that they really care about their students and are passionate about the school. It was comforting and i did not get the same impression from some of the other schools that I spoke with. The person who called to accept me was also so warm and informative.
But I haven't visited yet so we will see !!
