I applied online. The process took 3 weeks. I interviewed at Optiver
Interview
Online assessment, followed by HR interview where they want to know why you're interested in trading and Optiver. Final round is a super day with many technical interviews asking questions mostly to do with probability.
Interview questions [1]
Question 1
If I'm rolling a dice and add each roll to a running total, what number am I most likely to roll for the running total to go to at least 1000?
I applied through 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
