I applied through a recruiter. The process took 3 weeks.

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.
