I was actually on the very first day of interviews. There were only two of us. I was interviewed by the Director of Admissions and the other person was interviewed by a professor. There is a small writing prompt (10 min. time limit) before your interview but don't stress about it. Just make sure to emphasize why you want to go to ICO and what you could bring to the student body and field of optometry.
Campus is nice. Dorms are across the road from the college so really convenient. Responses from 1st years said profs were really approachable and down to earth.
