Ho presentato la mia candidatura online. La procedura ha richiesto una settimana. Ho sostenuto un colloquio presso Optiver (Amsterdam) nel mese di feb 2021
Colloquio
The first step in the interview process is an online hackerrank challenge and you have 48 hours to complete it. You have to choose between Java, C++ or C#. It is a mixture of theoretical and a few implementation questions. I completed the questions in February 2021.

Domanda 1
Validate a tree. I do not remember the question exactly but we were given a binary tree and we had to validate it given some instructions.

Colloquio
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
Difficult OA. Design question. Included min/max heap with lazy deletion + fib number sequencing + hashmaps all in one question. Easy techincal in comparison. Just don't stop typing during the OA and make sure to read everything carefully.
