Hi! I was just recently accepted to UH and the interview process was standard, I wouldn't say it was more difficult than normal. It can be intimidating to have 4-5 people interview you but really, it's an advantage because it gives the chance to have the conversation flow better and the time goes by quicker so there are no awkward pauses - just make sure you frequently make eye contact with everyone in the room even if you're answering a question 1 specific person asked you.
You'll probably be asked standard interview questions, "Why Optometry", "Why UHCO" . Depending on how the conversation flows after that they may ask you about certain grades or your OAT scores so be prepared to answer this - don't be intimidated by this question and don't get defensive in your response, you've already been invited to an interview so your stats have already been vetted. They're not trying to grill you just trying to get to know your life circumstances better. For example, if you had a particularly hard semester you can answer that you didn't do as best as you would've liked because you were also working or whatever your particular instance may be. There's always a positive to every situation and if you can emphasize what that positive is and what you've learned from it then that's what they're looking to hear.
I will say that during this interview I was asked an ethical question that I wasn't asked in any other interview, just make sure you answer from the heart and don't give any extreme one sided answers, always try to find middle ground.
Lastly, I would advise to ALWAYS ask 2-3 questions that relate to you or your interests at the end of the interview. For example, I am really interested in research and had a PhD professor on my panel so I asked about what "other" ways I could get involved with research aside from the traditional ways the school already advertised. You've been talking and answering their questions for half an hour and the panelists enjoy using this time to answer YOUR questions and talk about positive experiences in the school.
Hope you do great at your interview, don't sweat it, the faculty and staff are extremely welcoming and nice, so long as you're being yourself and are calm about answering any questions they have about your application file you should be golden! 🙂
