I interviewed at Illinois and VMRCVM and did both successfully.
VMRCVM's process is very, very different, but neither ask clinically-based questions and instead focus more on what sort of a person you are, your critical thinking & basic problem solving (to the best an interview can address these things), etc.
In general I focused on why I had decided on becoming a veterinarian, what challenges I anticipated, etc. Also knowing something about the school at which you're interviewing (what they like to see in an applicant, what sort of a student culture they aim for, their research emphasis and important researchers, what they're known for, etc) is helpful.
I'd also recommend looking up hot topics in vet med today (OneHealth is a huge buzzword, the importance of vets in emerging zoonotic diseases, international vet med, the recently formed caucus addressing vet student tuition, etc) just enough that you're conversational in them and aren't going to be caught open-mouthed if they work them into a question. And if they don't, you've got some pretty hefty information that
you can work into your answer.
