At the first stage there are 4 tests: coding test (Leetcode alike), probability theory (quite straightforward), predict the next number in the sequence (can be quite tough if you aren't prepared), mental games (quite easy, just don't panic)
Interview questions [1]
Question 1
Despite coding being quite easy (not much harder than div. 3 on codeforces), but to solve some of them you still need to rely on probability theory
I applied online. I interviewed at Optiver in Oct 2025
