Some i remember were: why optometry? explain any bad grades? How will you handle the stress of a 22 credit courseload/how do you deal with stress, what do you want to do with your optometry, how do you see optometry changing in the next 10 years? and they also asked me about my community service/volunteer experience.
It's a very laid-back interview, very conversational - just relax, let your personality shine through! Also, check out the interview feedback section - there should be a bunch of questions on there from Nova's interview. Good luck!
