Overall, it was quite a frustrating process. After passing an initial coding challenge, I was given 5 days to complete a video interview. The instructions for this interview were nearly impossible to understand, and I found the questions fairly insulting. It was very unlike the process at Citadel / Jane Street / Optiver, where you are given proper mathematical questions that require thinking.

Starts with a phone interview, then hr interview. Follows another technical interview and then final interview. Previous interviews are easy and quite smooth. The final interview requires you to interview with team members and team leaders where they will ask a lots of math questions.
