I applied online. The process took 4 weeks. I interviewed at Optiver (Sydney) in Apr 2021
Interview
Applied online and did 3 skills test - first mental math, second data analysis, third probability. For the most part, the questions aren't hugely difficult but the time pressure makes it tough.
After that there was a behavioural interview over zoom, then a final interview, also over zoom. The final interview had elements of probability and mental math, as well as behavioural and market making questions.
OA for Round 1, involves a lot of quick calculations and estimations. Behavioural interview, Technical interviews and final superday. Final superday involves many interviews, but I did not reach that part.
Interview questions [1]
Question 1
Why trading? Have you applied to any other places?
Multiple Rounds, first was behavioral and second was technical. They first did a pretty lengthy behavioral and seemed pretty good, but then the technical was mainly all Fermi estimations and market making games.
Online assessment followed by multiple steps of technical and behavioral interviews. Pretty standard process in general, positive experience. Seemed to care a lot about cultural fit more than other firms
