I applied online. I interviewed at DRW (Chicago, IL) in Mar 2023
Interview
Very odd OA. Nothing that was in the green book. There were some probability questions that were manageable and the Lin all was fine, but a few questions I have never seen before on any online quant interview prep resource.
The interview process includes a six-question online assessment testing coding and problem-solving skills, followed by an interview, then a superday with multiple technical and behavioral rounds, leading to a potential offer.
First I had to do an online assesment with five probability questions, then a 45 minutes interview with a trader in which i was asked some questions on projects and CV a market making game and probability questions.
