Lasm1990
Lasm1990, the NYC one was a lot of people, almost 40 candidates I think. It sounds like if you interview you were automatically invited for an assessment. Basically you get broken out into groups and then have to present a small case study they give you.
I think it's a tough way to evaluate candidates, especially with so many of us and so few evaluators (2), but that's how IESE does it. Wouldn't be surprised if I got dinged for not being overly enthusiastic like some were.
