Just wanted to update this for anyone looking in the future.
Although the interview is MMI style you should really heavily focus on preparing as you would for an actual interview. Personal details came up on all 7 of the doors. I wouldn't focus too much on preparing for ethical style questions but from what I've seen on other posts about preparing for MMI many advise that it's best to include personal anecdotes or experiences anyways within ethical answers.
We had a speaker go through a presentation. Then the group was split up evenly. While one group toured and did the writing prompt (very basic, standard optometry question) the others did the MMI interviews. We then switched. After that was lunch and then a tour of the clinic.
My interview was on a Monday and I was told the committee meets the next day on Tuesday afternoons. If you're accepted your portal should automatically update later that day and you'll be able to see the 'accepted' checklist. Official emails and letters get sent out on Friday.
Good luck to everyone! Overall, I'd say the MMI experience was an enjoyable one and a lot less intimidating than what I thought it would be. I'm not too clear about this but I was told the interviewers don't actually discuss anything they just have a scoring sheet where they rate you/add comments. This then gets sent to the committee. So I wouldn't worry about being repetitive between stations because each interviewer is seeing you from scratch. If I could do it again I'd repeat relevant information about myself in every station if need be and would focus on giving each interviewer a 100% well rounded image of yourself while still focusing on and thoroughly answering/addressing the prompt.
