I applied online. I interviewed at Optiver (Austin, TX) in Jul 2021
Interview
There are four processes Coding assessment, behavior, technical, final round
For the coding assessment, it was not much difficulty if you know about graph, tree. However, it takes a lot of time bc we need to think about many edge-cases.
Interview questions [1]
Question 1
One about sinple date calculate , the other one about graph
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.
They gave a long block of python code and wanted me to find the error in it, then wanted me to explain how I would make the system more scalable.
Application
I interviewed at Optiver (Amsterdam)
Interview
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
