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.
Other Quant Trader Intern interview reviews for Optiver
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
I applied online. I interviewed at Optiver (Amsterdam) in Dec 2025
Interview
Passed the online games and behavioral interview. Rejected at the Cognitive Interview phase. Failed because of not taking risk directly and second guessing if I'm doing things correctly. Overall challenging and fun experience.
