I put "no change" for my impression because I liked the tour and the students, but my interview was pretty bad. My interviewer was a pediatric nephrologist. He was friendly but had a thick accent - there were times he didn't understand me and that I didn't understand him. I hadn't anticipated a language barrier. I felt like I fielded questions well but am worried that he didn't get it all. He asked trivia questions but called them "common knowledge questions" and acted like he really expected me to answer them. And on the serious questions, I felt like he wasn't really listening. He asked me a lot of things that made be repeat myself. UNFORTUNATELY for me, the other interviewees had much different experiences: very relaxed with basic questions. Guess it's just the luck of the draw.
