Their class size is not very small, 90-100 students. Only schools out of the top of my head that has more is NECO, ICO & Salus. You have a lot of time, it's rolling admissions though so don't wait until March. Interview is pretty straight forward, exactly like what the previous people said. Check-in, interview one with open file, one with closed, one about prerequisites. Conversational, no technical questions about optometry. Don't stress, it's simply for them to gauge whether you have the social capacity, a lot of people can have amazing grades but can barely hold a 2 minute conversation without fidgeting or stuttering. If you speak clearly with concise answers and maintain basic things like posture and eye contact, you'll be hearing from the admissions office a week from your interview with good news.
