I applied online. I interviewed at DRW (Champaign, IL) in Sep 2020
Interview
First-round is four probability and statistics problems, not hard. Then I received codibility test with two coding problems. Both are easy level; however, I forgot to include the edge case and did not pass this step.

Question 1
Some Naive Bayes probabilities question.
Coding includes building a tree and decomposition a number into odd numbers
OA, HR interview, technical interview, superday. Everything was typical except the superday which was disorganised. Two trading interviews on mental maths, pricing options and brain teasers, as well as a coding challenge,
