WeRide interview questions

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.
