I applied online. The process took 2 weeks. I interviewed at Optiver (Melbourne) in May 2019
Interview
The first round is Hr screening and the second round is a technical interview with a software engineer. I don't know about the final round.
The HR was very nice and provided feedback for each round to me. All interviews were conducted remotely via Zoom calls.
Interview questions [1]
Question 1
HR: Behavioral questions like: why Optiver? what books do I read? And my interests...
technical: linear probing hash map.
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
