I applied online. The process took 3 weeks. I interviewed at Optiver in Feb 2022
Interview
Everything was great from the side of the company. During HR interview a lot of topics to revise for the technical interview were mentioned. There were not as easy questions as I expected.
Interview questions [1]
Question 1
Questions on your code from home assignment tasks.
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
