Sorry for the late response my biochem block ended last week, so we had an exam and a final back to back it was pretty hectic.
Perhaps
@luissepu5 could elaborate on his experiences but personally my UPR interview was focused on me. We pretty much spoke about things I’ve done (research, EC’s, my interests, etc.) In fact the second half of my interview was just me and the doctor chatting about wine and our travels. It was a very relaxed and informal interview that focused mainly on getting to know you as a person.
Since I assume you’ll be interviewing at other places I’ll give you a basic rundown on what to expect. I’m going to be purposely vague because some places asked me to sign a NDA. The medical information you need to know is very general. Have an informed opinion on things like euthanasia, medical marijuana, prescription drug abuse, the LGBT community’s relationship with the health care system, etc. In fact you could probably “wing it” and still do well as long as you can put together an intelligent argument. So basically, brush up on general issues to build your confidence but in the end what the interviewer wants isn’t to test your knowledge but your ability to reason.
Other formats you might run into are the MMI and group interviews. MMI was pretty fun for me, don’t be intimidated. It’s basically a series of short interviews or events to make you think on your feet. Again it’s all about your ability to reason and not a test of knowledge. The group interview has its pros and cons. The good part is that you can let others answer questions while you put together a response; the bad part is that if you go last the people before you might say everything you wanted to say.
