J'ai postulé en ligne. J'ai passé un entretien chez Optiver (New York, NY) en nov. 2025
Entretien
The OA had 3 parts: Sequences, Logic games, Probability theory. For sequences, there were 25 questions and times (around 50ish seconds per question max) with increasing difficulty. Logic games were annoying but self explanatory. Probability theory was just that.

Some logic questions were towers of hanoi, pattern recognition, risk management, etc
First you send your CV and then you get different "challenges". One for sequences, one for probability and one for coding. All of them are quite hard, especially the probability one.
