I have not had an interview there, but went through the pre-optometry workshop there last year and met Dr. Brown and others from UMSL-College of Optometry and all of them were so incredibly nice and informative on the profession and the schooling aspect, but very blunt in terms of what they expected and as the previous post said, the powerpoints on the website are there for a reason and in your best interest to know them very well. I have not received an interview from them and sadly I'm not sure if I will, especially since they are a phenomenal school, but best of luck to you and congratulations on your interview, remember just stay relaxed and be yourself, none of the people there are scary, they're all very approachable and down to earth and fun loving people who care about optometry, so if you are in that category you'll be fine..hopefully this was helpful even though I haven't actually went through an interview there.
