I applied online. The process took 3 weeks. I interviewed at Optiver (Sydney) in Mar 2023
Interview
It was five round of online questions and one behavioural and two techincals interviews. The questions are expected to be difficult but the behavioural round was friendly and what it was supposed to be a 45 minute interview ended up having another 15 minutes chatting about other subjects
a very typical intern interview, just ask u some normal question about ur background and why trading why the company
only general behaviour question, nothing about math or tech for the first round interview
There were many different mini games that did not immediately appear relevant to trading. The games during the interview appeared to measure confidence, technical skill, and how risk averse the candidate was.
