I didn't really get asked any questions other than what my goals were for the future. Since, I had atteneded the week-long internship, I got to know the staff well and when I went for the interview it was straight-forward and not many questions.
When I did the internship program, they held interviews the week I was there. I got to talk to some of the students that were applying then and get some feedback from them
What was the most difficult question?
There were no difficult questions. I know that theose who did not attend the intership program were asked more questions and the interviews lasted longer
