I think the interview is hard for someone with less technical background. Even though they said that candidates with different disciplines are welcome, I do not think it is the case.
Interview questions [1]
Question 1
Several rounds. I believe the sources online at this point is enough.
Fast communication with recruiters including notifying you of your status. Little Feedback on the quality of the work was provided. It began with completing a small assignment utilizing Excel and then having it sent back.
I applied online. I interviewed at Jane Street (London, England) in Dec 2022
Interview
Simple and fast, they tell you if they dont want you quite quickly. People are very nice. I got referred by my friends but i dont know how much that helped me
