J'ai postulé en ligne. Le processus a pris 2 semaines. J'ai passé un entretien chez Optiver (Londres, Angleterre) en août 2025
Entretien
Online HackerRank question - given requirements and have to implement a class that represents a certain system (not that algorithmic)
Then behavioural interview with 2 members of HR, fairly standard.
Questions d'entretien [1]
Question 1
Why work here?
Explain your background.
Tell us about a time that you failed or didn't meet expectations and how did you deal with it.
What would others say is your weakness? (Soft skills wise)
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.
