I applied online. The process took 2 days. I interviewed at Optiver (Sydney) in Apr 2023
Interview
It was fun, but unnecessarily long and difficult that does not test what the job actually needs (e.g., who on planet earth even cares if you can do (117 x 7) in 5 second or not and not sure how relevant it is for the job as a trader).
Interview questions [1]
Question 1
I only got to do the first step of the interview process, which is an online test that lasts about 3 hours and has about 4 stages to it. It consists of mental math and a bunch of games, then at the end there are some brainteasers/prob. questions and behavioural questions. If you pass this first online step, you would be scheduled for a behavioural interview and then a final deadly difficult interview for about 3 hours.
I applied through college or university. The process took 2 weeks. I interviewed at Optiver (Amsterdam) in Mar 2026
Interview
Did the online assement, sequences test, Zap N and lastly beat the odds probability type questions. The Zap N was some working memory, reflexing and planning tests and the beat the odds focused on giving good approximations to probabilities in around 1.5 minute for each question. Then did the technical which focused on market making games. Unfortunately, I was rejected after this round so don't much more than this.
The process took 2 weeks. I interviewed at Optiver (Amsterdam) in Jan 2025
Interview
first round: assessment with sequences, a variety of games testing memory, reaction speed, then a behavioral interview and finally a technical interview where we played a market-making game. The market making game included cards, you had to decide to buy/sell, what quantities etc. Assesment and behavioral where passable, technical was really difficult.
it almost took more than 2 hours to finish the online assessment, then a hr interview with typical behaviour questions. online assessment is not easy, including mental mathematics and logical reasoning questions. Hr interview is quite relaxed
