J'ai postulé en ligne. J'ai passé un entretien chez Optiver en oct. 2025
Entretien
Online Assessment,
Round one was interview with a trader to do some gambling game. Buy on coins, dices or cards. Explain your strategy to maximize gain in short time.
Round two was solving probability questions with a trader. Didnt pass this round.
Questions d'entretien [1]
Question 1
2 questions. bus waiting question:
Buses coming at 10 min intervals, expected waiting time.
Then if 50% of buses late fo 5 min, expected waiting time.
At the first stage there are 4 tests: coding test (Leetcode alike), probability theory (quite straightforward), predict the next number in the sequence (can be quite tough if you aren't prepared), mental games (quite easy, just don't panic)
Questions d'entretien [1]
Question 1
Despite coding being quite easy (not much harder than div. 3 on codeforces), but to solve some of them you still need to rely on probability theory
