I applied online. I interviewed at Optiver (Singapore) in Sept 2022
Interview
The interview process consisted firstly of a technical challenge. I was not able to complete it on time as I did not pass all test cases. Needless to say, I did not proceed with the later interview rounds.
The interviews consisted of an OA, then behavioural, then technical and thena final round consisting of another technical, system design and behavioural. These last interviews all an hour each. I only got up to the first technical.
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
