I applied online. I interviewed at Optiver (Amsterdam) in Jan 2021
Interview
It was a skype interview with the HR. The interview mainly consisted of questions about myself and about why would I like to work at their company. Is was not a technical interview. I recommend to do some research on the company beforehand.
Interview questions [1]
Question 1
The most interesting questions was "how will it be if there were 5 of you in the same room working on a project"
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
