Interview Process
This was a phone screen interview where the interviewer asked me to implement a rate limiter. The goal was to limit the number of requests from a user to a certain threshold within a specific time window. We discussed different approaches such as the token bucket and leaky bucket algorithms. I implemented a basic version using a sliding window approach. The interviewer provided me with some input cases to test my implementation. In addition to the coding challenge, we discussed behavioral questions regarding my experience and projects I’ve worked on. Overall, the interview lasted about 26 minutes.
