In college I interviewed at a commodity trader and they made us play a group trading game, I bombed because I wanted to make sure every trade I made was profitable/certain, people who made it to the next round moved quick even if they made somewhat questionable trades. That's when I realised I was not meant to be a commodity trader where decisions need to be made in matter of minutes. It was just so different from the business case interviews I was also doing at the same time where you build a thesis and stress test it and look for areas you missed
