J'ai postulé via un recruteur. J'ai passé un entretien chez Optiver (Chicago, IL) en déc. 2025
Entretien
The interview process at Optiver typically starts with an online assessment (OA), followed by an HR screening call, and then more technical interview rounds.
The first technical round I experienced involved implementing a queue data structure and discussing different design choices. The interviewer placed strong emphasis on trade-offs between various methods, such as time complexity, space usage, and scalability. The discussion was interactive and required explaining reasoning clearly rather than just producing working code.

Question 1
Implementing a queue data structure and discussing trade offs
A bit anxiety inducing, there were two developers observing and asking questions. Real-time problem solving required, conducted on Hacker Rank virtually, video and mic enabled - quite nervewracking to say the least
I had one round, which was an online HackerRank test. I wasn’t able to pass all the test cases, and as a result, I did not progress to the next stage of the process.
A lot of interviews. Started off with a call, then some online tests. Then a technical interview. Then a live coding interview along with a architecture interview. Last step would have been final day interview but I did not get that far.

Question 1
How many bits do you need to store a number up to X. And how can you represent that.
