Oh also, the confidentiality agreement encompasses the questions - so, nobody is allowed to tell you what questions they had on their MMI. It's especially not smart to say what they are on a public forum
There are examples freely available, and those are obviously fine to talk about and practice with (and a fairly decent indicator of the types of questions a typical MMI will ask).
I'm honestly not sure if the confidentiality agreement encompasses the general types of questions that are asked, but it might be okay if someone only says yes/no? I'm really not sure. Definitely don't expect specifics though; you don't want to get people in trouble. Professional schools tend to take that sort of thing rather seriously.
