I applied online. I interviewed at DRW in Sept 2021
Interview
The interview is a three-step procedure that takes a month: OA, phone interview, and super day. The super day is held in groups of 30 people to host an open ceremony and introduction to DRW while the candidates are interviewed individually. The phone interview lasts 45 minutes and includes a combination of behavioral and technical questions (mostly technical). And there are many interviews scheduled throughout the super day, all of which are dependent on the interviewers (though I'm suspicious that they allocate interviewers based on race, such as matching Asian interviewers with Asian interviewees). If you have a smart-looking man as your interviewer, he will almost certainly ask you some tough questions. So be ready for it. There is a coding challenge prior to the super day in which you must solve a prediction problem on a clean, tiny dataset (no need for feature engineering). If you do well on the super day, you will be scheduled for a follow-up conversation to discuss your history and determine if you are a suitable match.
Interview questions [1]
Question 1
A middle point between the top hedge funds and market-making firms. You will still be expected to solve a lot of brain teasers and display clear and intuitive thought processes to answer stressful and difficult questions. However, there is no need to be concerned about speed or mental math. They may ask questions from the green book, so go through the questions in it thoroughly. Also, be prepared to answer questions on linear algebra, probability, and market-making.

Interview
Zoom Video Interview
This interview lasted ~1hr with a junior Quantitative Trader.
Was asked Bayesian probability, Markov Chains, motivations for DRW, why I am a good fit for the job.
Application online, OA, screening call. did not make it past the screening call with HR rep so cannot speak to rest of process but first 3 were fairly straightforward and not too hard at all
I applied online. I interviewed at DRW (Singapore) in Sept 2023
Interview
The first stage was a take-home technical assessment containing a single programming question. While I was given almost 2 hours to solve the problem, I solved it in slightly under 30 minutes, and spent the rest of the time being paranoid about whether my answer was sensible.
The second stage was a pleasant informal call with HR.
The third stage was a video call with two quant trading analysts, who asked some simple probability and statistics questions. I fumbled and didn't get to proceed any further.

Question 1
Binomial distribution (need to know mean and variance in closed form), and linear regression.
