Sales and Trading Summer Analyst

First was a phone screen that was pretty standard in terms of behaviorals and basic motivational (why S&T?, why CITI, etc). I think I got to this point by networking beforehand. Then there was the superday which included 3 interviews. 1 involved a case study that involved assessing various investment options (involving equities, commods, and bonds) as a "portfolio manager" amidst some macroeconomic conditions). Another was a bit more technical about markets asking for my opinion on various market things like the current outlook, rates, and my outlook on economies around the world. The last was again more behavioral/motivational.
