I applied online. The process took 4 weeks. I interviewed at DRW (London, England) in Oct 2024
Interview
OA -> Technical Interview -> Onsite interview
OA was 3 leetcode questions, easy-medium. Might have gotten lucky.
1st Tech interview was about CS fundamental questions, a little bit about about data structures and algorithms. Be sure to be prepared for implementation details for common data structures.
Also some bits about how computers work down to the hardware.

Question 1
Questions are about CS fundamental questions. Should be fine if you studied a decent Y1 course in CS.

Interview
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.

OA then first round interview in 45 minutes. The interviewer is friendly and helpful. They mostly ask about C++ knowledge and low-level details, rather than leetcode questions. Got rejected after that.
