Interview Process
The interview consisted of a technical discussion focused on system design. The interviewer asked the candidate to design a rate limiter, which included explaining the use of a token bucket algorithm to manage request rates. The candidate discussed trade-offs between memory usage and precision, as well as the implementation in a distributed system while considering synchronization issues. The discussion also covered real-world scenarios where rate limiting is necessary, such as API usage to prevent abuse, and edge cases like burst traffic and potential attempts to bypass rate limits.
