Hi! I had a successful MMI experience but I was very uncertain of how to prepare for it beforehand. If I had to do it all over again, this is what I'd do....
I didn't practice any acting scenarios. But I would think the important thing would be to verbally assure the person that you hear them, you empathize with their situation, ask them what they would like/need and be observant of your surroundings etc...
If you're like me, your nervousness primarily stems from the fear that they'll ask you the one question that you don't have a good answer to. For me, that question was the " what is your biggest strength/weakness" scenario. For you, it might be a different question/questions. Attack these questions first in your prep. Make the conscious effort of writing out your responses and practice saying them out loud.
Next, I felt like I was weak on my answers for ethics-type questions. I found a fantastic website (recommended on SDN) that has many case scenarios with different topics AND how to answer these questions. This is the link:
http://depts.washington.edu/bioethx/topics/index.html
I read all the cases and managed to discern specific patterns in how such questions should be answered.
Of course, it's a good idea to be familiar with the Affordable Care Act (i.e Obamacare). I found a little silly Youtube video that helped me get a basic idea of it:
Then, do some research as to how the ACA is being implemented in the State of the school you are interviewing (i.e the Supreme Court ruled that the expansion of Medicare will be decided individually by each State etc...) This will expose you to the pros and cons of ACA as it applies specifically to your State-of-interest. This will help you answer ACA-type questions. For instance, if you're asked how expanding Medicare will affect healthcare in the long-term, you'll give a more informed, personalized answer if you know whether your State even plans to expand Medicare etc.
Keep in mind that these interviewers will probably have never seen your file/ they don't know anything about you. Interject personal details in your response when appropriate. For instance, if they ask you a question about end-of-life care and you've worked as a Hospice volunteer, work that into your response. You want to be memorable.
Finally, keep in mind that some interviewers may be less engaging/responsive than others. Assume that they are doing this on purpose and are trying to see how you react under stress etc. Don't let them mess with your head.
Some people above stated that "prepping" for MMI's is pointless. But for me, the very practice of reading ethics cases/studying up on ACA/purposefully addressing my weaknesses got me into the "zone" and my confidence increased dramatically. I still had some nervous jitters but I kept reminding myself that I had prepared well and I could at least speak a little on any major topic.
Good luck!!
