Citi Trainee position



I will be doing a group dynamic (this might not be the right term, since I’m translating it literally) in 2 weeks for a trainee position at Citi. Btw, it’s a position for a country in Latin America.
I was wondering if anyone had an idea of what to expect. I’m assuming there will be some sort of interview or case study (or some combination of these).

Any help will be appreciated.
