Interview Process
The interview began with a brief introduction and questions about my background. The interviewer then presented the Rate Limiter problem, a common topic in system design interviews. I was tasked with implementing a rate limiter for an API that allows a maximum of 100 requests per minute from a single user. The interviewer was encouraging and provided hints on how to approach the problem. After discussing my initial thoughts, I implemented a token bucket algorithm as a potential solution. We then discussed possible edge cases, such as handling bursts of requests and resetting the user’s count at the end of the time window. Overall, it was a positive experience, and I felt I was able to showcase my problem-solving skills effectively.
