I had my interview this morning and I think it went very well. It was with a career management member. As others said before it is not to trick you but to test your interest.
We went over the regular questions : why MBA now ? Why Ivey ? How can you contribute ? Talk to me about yourself and your resume ? What do you do in your current role ? How did you move the ladders in your job ? Why your teammates would recommend you ? etc
So as long as you're prepared for these questions and can come up with examples it should be fine, it's really not to trick you.
Beside there were a lot of personal questions like why did I study for the CFA, etc.
Good luck for all of those who will be interviewing soon, I hope it goes well !
