I had what i thought were pretty good interviews at two ivies and several top state schools. I got waitlisted and later rejected at all of them.
At one school, my interviewer even invited me to shadow them in the clinic after the interview. I still got waitlisted and was rejected 2 days ago.
People have what they perceive as "bad" interviews and still get in, People also have what were "good" interviews and dont get in. Its pretty much a lottery in the end
Im just one person so its not like everyone has as bad luck as i did last cycle. Everything happens for a reason and Im pretty happy where i ended up this fall.
