TL;DR - PRACTICE!!!
So quick disclaimer, I did receive an interview invite to UNM but eventually declined it because I got accepted to a different program (which did not use MMI, but I am still waiting to hear whether I got an interview at a school that does use MMI). The invite email I remember had two videos about the MMI format; did you watch those? They’re a good starting point but they’re more for information only (i.e. what is MMI, what is the purpose, etc.) and not really that good at helping you prepare. The thing that is most helpful is practicing using sample questions.
First, I found a playlist of sample MMI questions and answers:
MMI Practice Scenarios - YouTube IMO the speaker talks/writes too slow so I watched these at 1.5x speed, but do what works best for you. Note that the questions he uses are from the University of British Columbia’s medical school, so they may not all apply to U.S. pharmacy schools. But the most important thing to take from the videos is how he works through the problems and possible solutions. In general, the format he follows is (1) state the problem in your own words; (2) collect additional information about the problem; (3) restate the problem again; (4) identify possible solutions, even if you know it’s the “wrong” solution; and (5) explain which solution(s) is best and why. The first video in the playlist, “The Gym,” does a really good job at illustrating all these steps, though personally, I think step 3 should be optional. The reason this is important is because you’ll have several minutes of talking time at any given station, and, counterintuitively, you don’t want to simply state your answer. Instead, you want to show how you arrived at your decision. It
is a critical thinking exercise, after all.
Second, now that you know how to answer an MMI question, practice them yourself! You can easily find hundreds of sample MMI questions online, so pick a few and practice them like you were in a real interview (you can even pick questions from the above-mentioned playlist, pause to answer, and then see how they answered it). That means allowing yourself two minutes to read the question and prepare and then
answering the question out loud. You can choose to have an audience or not, but it’s important that you’re
answering out loud. It might feel a little silly to be interviewing yourself in the mirror or in front of your friends, but we’re all perfect interviewees when we only practice in our heads.
Speaking out loud will allow you to better identify your strengths and weaknesses. Oh! And I forgot, also time yourself while you’re speaking. You want to make sure to fit within about 6-8 minutes so that you’re concise enough to fit in all your thoughts, but also aren’t awkwardly sitting there with your interviewer when you’ve run out of things to say too early.
Lastly, it is possible that a few stations will ask traditional interview questions, like why you want to be a pharmacist, so don’t neglect practicing those questions either.
I hope this gives you a good starting point, and good luck with your interview!
