I had my interview for PCO earlier this month. Actually just a few hours ago today I got my acceptance email- I'm pretty excited since PCO is my first choice! Now I just gotta wait for the official letter...
As far as how my interview went, the professor was more interested in talking to me about optometry in general, my reasons for wanting to be an optometrist, and my experiences in college rather than the form he had to fill out while we talked. I was still kinda stressed out about it, but keep in mind that they just want to get to know you.
As far as what to do beforehand, look up some information about the school- I paged through their student guide the night before and checked out the coursework and all that. Look through the website too. My interviewer also wanted to know my opinions on corporate optometry (the $40 eye exams in Wal-Mart and stuff like that...)- if you've done any shadowing I'm sure the optometrist talked about corporate vs. private optometry a little bit. Also be ready to answer the "what about ophthalmology?" question.
I shadowed 3 optometrists for a day each, they each were really great for talking about the field and their opinions on problems etc. that optometrists face today. They also let me sit in on exams, which let me see each person's style of practice.
Google "med school interview tips" or something like that for other advice, you can find some good questions to ask the interviewer- since they always ask if you have questions at the end.
