Hey everyone. I just had my interview today for U of T MHI and am armed with answers to many of your questions here:
1. What to wear: I went with business "casual" (suit without the blazer)
2. What to prepare: for the presentation they really want you to focus in on a specific topic or issue. Do your research, show how you think, and you will do great. Print your powerpoint presentation as all slides on one page and keep it simple (they need to be able to see the slides but also listen to what you're saying). I also printed notes for myself to read off of. It isn't an actual "presentation", you're just sitting in a room with one other person while you go through your slides on paper.
3. What to expect:
The written question was a bit vague, so your answer will really depend on how much you know about health informatics in general. 20 minutes was more than enough time to fill a page of writing in my opinion.
The interviews were as follows: 3 interviews in total, about 15 min each. 1 interviewer will listen to your presentation and ask follow up questions. The other 2 interviewers (whom you will see one at a time) will ask you questions about your background and analytical skills.
Let me know if you have any other questions!!
