I did an OA, then a first round, then went to the final round 1. I heard there were 4 final rounds in total. The questions I got were similar to what other people posted on Glassdoor, so good on you if you're reading this. The only thing I'm not happy about is that they don't give out feedback even though I reached the final round.

Technical Case

After applying, I took an online exam that lasted about an hour and was entirely multiple choice. They gave me study material about the order book beforehand. The next round was an online interview, which was unexpected. I was given a problem and allowed to brainstorm and think through it with the interviewer for about 45 minutes on Zoom, including introductions and their questions. The interviewer was very patient and listened well, even when I was thinking out loud and got a bit lost. It was a fun experience, and I enjoyed discussing a random topic and brainstorming. I haven't heard back yet.
