I applied online. I interviewed at Five Rings (New York, NY) in Oct 2023
Interview
HR math + 2 rounds of Technical by trader; last round interviewer did not open camera and gave a formulaic wise difficult problem (told me no trick behind & purely testing if you can list out all possibilities carefully)
Interview questions [1]
Question 1
1min per question HR round; no bq at all trader round
Had an OA but I thought I didn't well but I passed. I think I got lucky cuz I didn't cheated. Just don't cheat, there is no point doing that. First and second round the interviewers were all nice and the problems were very interesting and thought-provoking. Had a good experience with the five rings.
Lots of probability and brainteasers. Fairly difficult but very interesting. First round is iffy because can be hit or miss depending on your estimations. Reminaing 5 rounds went well. 1 to 1 interviews with existing traders
