Hey there mieuw,
First place I'd look is right here - >
MIM Interview ExperienceThe forum there itself is quite useful - the fellow who runs it answers regularly and helpfully.
Secondly, for my part, I'd say be ready to answer any question that might be derived from what you put into your application file. What I mean is: you could be asked about your extracurricular activities or any international experiences you might have had, or your opinion on some current event. I got asked about my experience in Central Europe as an intern, and about one of the sports I put in extracurriculars and how it helped me grow as a person, if at all.
There really is no set list of questions, mind you - just be calm and answer confidently and honestly and you should be cool. I came out the interview feeling a bit unsure about how I did, though fairly certain I had presented myself honestly and cogently, and turns out I did really well.
Good luck, and don't sweat it!
