J'ai postulé en ligne. Le processus a pris 3 mois. J'ai passé un entretien chez Optiver (Amsterdam) en déc. 2025
Entretien
I completed the online assessment in September and was invited to a behavioral interview in December. The interview felt quite rushed. The recruiter interrupted me frequently, which made it difficult to fully explain my answers or demonstrate my reasoning. She did not seem very interested in hearing my responses and appeared eager to finish the interview as quickly as possible. I had a strong feeling immediately afterward that I would not move forward, which was confirmed by a rejection the next day.
OA; quite long, 3 tests
Behavioral interview: just a short talk with HR, motivation,…
Technical Interview 1: fundamental CS, nothing more
Technical Interview 2: system design, very vague but just go with the flow
Technical Interview 3: live coding, still leetcode but optiver style is a very descriptive problem, but the main thing could be boiled down into only few lines
Difficult OA. Design question. Included min/max heap with lazy deletion + fib number sequencing + hashmaps all in one question. Easy techincal in comparison. Just don't stop typing during the OA and make sure to read everything carefully.
