Idiots who try a lot while not contributing to the mock pbl interview
What did you wish you had known ahead of time?
Just talk a lot and contribute to the discussion. Don't say random things that are not on topic. Here's an example, when discussing the "learning idea," say relevelant information like studying the mechanism of birth control pills not something like "she got pregnant."
What are your general comments?
It takes a little luck to get a group where there are a few timid individuals. If you are naturally loud and love speaking, you'll excel at the interview and get in almost for sure. If you're in a group where everyone is really good then you better have good grades to get in. I'm pretty sure they evaluate your performance against others in the room.
