Reviewed faculty information; reviewed list of possible topics on school's website.
What was the most difficult question?
Imagine there is an extremely good class coming in, with academic scores higher than or around yours. Seventy-nine out of eighty have been selected for your class. You and five other people are given the opportunity for a second interview. Why would you make a better candidate than the other five?
The interview is two people, where one knows your grades etc and the other knows nothing about you. My one interviewer, who must have looked at my marks and didn't want me to try to use them as a talking point, told me that he was supposed to have looked at data but he chose not to and would leave it to the admissions committee. It didn't hit me until I was told "no, there's no way he can breach protocol like that!" later on, I actually thought that my entire interview was closed-file. Dr. Higa is very tricky!
What impressed you negatively?
I wish that we were given an opportunity to meet more of the faculty, asides from the two interviewers.
