How well or poorly the interviews go is totally dependent on how much the interviewee and the interviewer have in common. Some people will connect and things will go great (as with my second interview, where we only stopped chatting because my interviewer had a meeting to get to), others will struggle to find common ground (like my first interview, which lasted 25 minutes and consisted of rather halting conversation). Still, I felt like both of my interviewers managed to get a sense of what I had to offer the school and my peers.
