It's a super chill interview. Like everyone else says, it's very conversational. They ask you the standard questions i.e. why optometry? and then they go over your file. No grilling. They will ask about any outstanding prereqs and when you plan to finish them. I had this disaster where optomcas forgot to put in my AP credits that fulfilled my calc prereq, but the interviewer was super nice and just let me pull up my transcript for her to see that I fulfilled all my prereqs. My interviewer was not an OD, which is possibly why it was a little more relaxing. The tour is super long though, and you will get hungry. It requires a lot of walking and they also drive you to see their clinic. They provide free lunch. Their cafeteria and lunch was my fav part of the tour. Wear comfy shoes. If you aren't used to Northeastern US weather, make sure to dress appropriate. Scarfs, parkas, hats, etcs. I do not recommend wearing a skirt suit and opt for pants if you are a females. They get decisions back to you within 2 weeks. I was admitted last month into PCO but will be attending SUNY come August.
