Hiring great people is hard. So we spend a lot of time and energy trying to get it right.

We also understand that interviewing is hard and can be stressful, whether you’re looking for an internship, or something more permanent.

We get questions all the time about hiring – when should I apply, what do you look for in an application, and what should I expect once I’ve been selected to interview. We’ve answered this last question a few times about our software development interview process, but haven’t said a lot about our other interview processes up to this point.

So we’ve put together an introduction to some of the things we test for during our quantitative trading and research interviews. You’ll find a guide here that includes the basic concepts we ask about – probability, expected value, making markets – and a little context as to why we care about them. This isn’t required reading by any means, but we hope it helps those of you who have been curious about how to prepare before sending in an application or interviewing with us.

If this is the kind of thing that sounds interesting and fun to you, you might want to consider applying. If this is all new to you, don’t worry– you’re in good company. We all started somewhere. Try some practice problems and apply when you feel like you have a better handle on all of this. We’re happy to hear from you whenever you’re ready. Either way, we look forward to interviewing you soon!
