I applied online. The process took 2 weeks. I interviewed at Optiver (Chicago, IL) in Jan 2022
Interview
First was Pymetrics and then a zoom interview. The Zoom interview was very difficult: at first it was simple math questions and then they gave a market making exercise that would have been doable in 5 minutes but they gave a minute and a half. I knew my statistics and expectation and all the tricks with that but not well enough.
Interview questions [1]
Question 1
Basic why are you interested in the firm behavioral question and then straight to technicals.
It was a very rough process overall, they asked some difficult questions about probability, making bets/ trades on certain scenarios, requires being able to estimate large/small numbers, giving confidence intervals
I applied online. I interviewed at Optiver (Amsterdam) in Nov 2025
Interview
Online Assesment, then 30 minute zoom call with HR person, then 2 60 minute technicals and finally 60 minute final technical and 60 minute final HR. Online Assesment was mix of reflex games (can't really practice these), pattern recognition in sequences and probability estimations. Pattern recognition ones are 90% of the time one of few tricks. Probability ones are usually impossible to estimate accurately (no clean solution), but the gap between answers is usually big enough for it to not matter. All 3 technical interviews were me playing some kind of market simulator with a trader, and him asking questions about my thought process. These games did not require knowing more advanced concepts than EV.
I applied through college or university. The process took 2 weeks. I interviewed at Optiver
Interview
Online application -> behavioural interview -> cognitive interview 1 -> cognitive interview 2 -> assessment centre - which is a mix of technical and behavioural questions. The entire process is online.
