The interview process was incredibly fair. Throughout 3 rounds I spoke with a variety of team members from analysts to MDs, all of whom seemed concerned about my well-being and happiness at the firm. There was a mix of technical and behavioral questions, but nothing that you wouldn't expect preparing for banking interviews at other MM/EB/BB firms. Based on the other analysts, it seems they recruit primarily from semi-targets and target schools.

First started with a very technical phone screen, a model test, another interview, and ultimately an invite to their SF office. Keep doing your studying for the IB guides but if you get invited to the SuperDay, plan on mingling and getting drunk with the other analysts. I think I ultimately got dinged for leaving the bar early to make a 4AM flight instead of sacking up and pulling an all-nighter.
