I applied through a recruiter. The process took 3 days. I interviewed at Saber Interactive (Minsk) in Jan 2021
Interview
The interview was relatively standard and lasted around an hour and a half. It focused heavily on low-level questions related to C++ and operating systems. Before the interview, there was a short test assignment consisting of three easy/middle difficulty tasks.

Question 1
They asked about how L-level CPU caches work, particularly in the context of multithreading. Also covered memory organization in the OS, concepts like memory pages and related mechanisms.
