Interview Process
The interview started with a brief introduction, and the interviewer asked about my experience with rate limiting. I explained different rate limiting strategies I have implemented in past projects. Then, the interviewer provided a scenario: we have a service that needs to handle requests efficiently while not exceeding a certain threshold. They asked me to design a rate limiter for it, and I discussed the token bucket algorithm, explaining how it works and why it might be suitable for our needs.
After that, I was asked to code the rate limiter in Python. I implemented the logic and explained my thought process as I went along. The interviewer asked for edge cases, and I discussed handling burst requests and how to maintain fair access across users. Finally, we wrapped up with some behavioral questions about my past experiences working collaboratively in teams, providing examples of conflict resolution and effective communication. Overall, the interview was smooth and the interviewer was friendly.
