For 2025 summer. Online assessment with tons of mental math, sequences, basic probability questions. Then pymetric stuff testing reaction speed. Lots of good guides online. After that techinical round with trader, HR, and final rounds.
J'ai passé un entretien chez Optiver (Chicago, IL)
Entretien
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

Entretien
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.
J'ai postulé via un établissement d'enseignement supérieur ou universitaire. Le processus a pris 2 semaines. J'ai passé un entretien chez Optiver
Entretien
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.
