Interview Process
The interview process started with a recruiter call, followed by a technical phone screen. In the first part of the phone interview, I was asked to explain how I would implement a Rate Limiter. The interviewer was looking for an understanding of various algorithms and patterns for rate limiting, such as Token Bucket and Leaky Bucket. After discussing the theory, I was provided with a problem that required implementing a rate limiter in code. I chose to implement the Token Bucket algorithm in Python. After implementation, I explained my code line by line, covering edge cases and performance considerations. The interviewer was engaged and asked follow-up questions about how I would test this implementation in a production environment. Overall, it was a challenging but fair interview, with a good mix of theoretical knowledge and practical application. I appreciated the interviewer’s style, which encouraged me to think aloud and collaborate on the problem. I’m currently waiting for feedback from the next stage.
