The interviewer started with some C++ fundamentals, including the principles and usage of smart pointers, as well as C++ multithreading/concurrency topics such as how to solve the producer-consumer problem. Then there was a coding question: a server has resources to support a certain volume of requests within a given time window, and you need to write a class that determines whether the current request has enough resources available. This can be solved using a token bucket algorithm.

This stage typically includes multiple rounds of interviews with different team members. For technical roles, expect to discuss algorithms, data structures, system design, and possibly work through coding problems on a whiteboard or shared document. For non-technical roles, expect in-depth discussions about your past experiences, situational questions, and how you approach problems and projects.
