J'ai postulé via la recommandation d'un employé. Le processus a pris 2 semaines. J'ai passé un entretien chez Optiver en nov. 2017
Entretien
The inverview was a three step process: a hackerrank test, a skype call and an onsite interview. The HR was very quick to respond and I was some with my process within 2 weeks.
Questions d'entretien [1]
Question 1
1) Questions about abstract and virtual functions (difficulty: easy)
2) Questions on computing the time complexity of an algorithm (difficulty: easy)
3) An algorithm was described and a data structure had to be chosen for the task (difficulty: easy)
4) Select the 3rd largest date from a list of dates (difficulty: medium)
5) You are given a string which describes a binary search tree, for example: (A, B) (B, C) (C, D) ... where each tuple denotes a (parent, child).

As soon as my CV reached them, I had 7 days to complete a HackerRank and 2 more tests. It took them from Monday morning (when I submitted the coding test) to Wednesday evening to reply.

Question 1
Was a Hacker Rank average but difficult, then a CS questions in multiple choice and finally some kind of minigames.
After I applied, I received an online assessment shortly. It was hacker-rank styled. I had only 2 choices of language - C++ and Java. A bit difficult than average, but doable with a lot of practice.
The original assessments consisted of:
- A coding test (1 hard question) which takes approx. 75 minutes
- A coding knowledge quiz
- Zap-N, a set of short neuro assessment games

Question 1
The coding test question was very difficult. Required a great understanding of data structures in programming and problem solving
