J'ai postulé en ligne. J'ai passé un entretien chez Optiver (Amsterdam) en nov. 2023
Entretien
The process starts with a test consisting of four parts. First part is coding, second part logical games, third part sequences, fourth part simple probability question.
To me the coding part was hardest which included two questions, the
first one was on dynamic programming, I didn't have time for the second one.
Questions d'entretien [1]
Question 1
Probably the hardest probability question:
In a family the parents make children until they have more than one girl than boy. What is the expected number of children in this family?
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.
