The interview is 2:1 so there's a professor and student that joint interviews you. For me, there wasn't enough students so I only had a professor interview me. I'd say the questions from the link above is the best way to prep. I'd say the questions are more personality oriented but they ask optometry field questions to gauge your enthusiasm. Nothing hard though. The day lasted about 4-5 hours. They hand your acceptance at the end of the day...Good luck!
