I applied online. I interviewed at DRW in Sept 2021
Interview
The coding round had 4 easy to medium level questions. The time given to solve the problem was 2 hours 30 minutes. Most of the questions were easy apart from the last one. The last one was a bit time taking and lengthy

Online Coding Assessment. Aced it but they didnt contact me after. It was about 2 hours long but I took 1 hour. Got the rejection notification a couple days later.
Codility online assessment was the first round which was leetcode style. Then a technical interview and then a superday. Technical interview entailed multiple questions on various topics such as algorithms, data structures, os, networking, system design and more.
