I did a 2.5 hour coding assessment that requires access to the video and audio. The questions were not bad. Got rejected in the next working day and did not get to the next stage.
I applied online. I interviewed at DRW (Montreal, QC) in Jan 2026
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.

I applied online. The process took 4 weeks. I interviewed at DRW (London, England) in Oct 2025
Interview
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.
