J'ai postulé en ligne. Le processus a pris 2 semaines. J'ai passé un entretien chez Optiver (Amsterdam)
Entretien
The whole OA process is quite lengthy, it consists of a 2 hour coding question heavily focused on OOP design. A 20 minute multiple choice question about general programming and computer systems knowledge. About one hour for their cognitive minigames.
Questions d'entretien [1]
Question 1
These were some of the MQ questions I got in the second phase:
- In context of relational databases, what does 'Normalisation' refer to?
- What is the estimated overhead of system calls on Linux?
- How can false sharding be fixed in a multithreaded program?
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.
