Just adding on to wikais and optogirlkp. The interview is very casual, just like any conversation. My interviewer was very friendly and said she would put in great words for me to the admissions committee. I guess she was really impressed. I thought the interview went by really quickly but when I came to the waiting room I realized that it had been 45 minutes. Most of the interview involved my interest in optometry and PCO, make sure to do your research so that you know WHY you want to go to PCO, she also asked me about some of the courses I struggled with in Undergrad so make sure if you have any courses like that, you give a good explanation as to why you struggled. Good luck!
