Fui entrevistado pela Optiver (Amsterdã) em jan. de 2021
Entrevista
First you have a Hackerrank, but it's not really the leetcodey type, you have 2 days to submit it.
Then HR interview, which is a big filter so you need to prepare for it.
Then there was a technical interview going over the Hackerrank and talking a bit about system design and fundamentals.
Finally there was the superday with 1h on cs/math fundamentals (again, not leetcode stuff, more about problem solving), 1h on system design (ask LOTS of questions) and then 1h of non-technical / project presentation. Also got to meet the CTO and to speak with one of the former interns.
Expect the interviews to be pretty tough, not really for what concerns prior knowledge, but more about being able to think on your feet.
They appreciated interest in the company and in the industry.
The process is very long but I received quick and detailed feedback.

Pergunta 1
I am not allowed to share specific questions, but know your CS fundamentals and don't focus too much on DS&A
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
