Interview Process
During my phone screen with Roblox, I was asked about the Rate Limiter problem. The interviewer wanted me to discuss and implement a solution for limiting the number of requests made to an API within a certain timeframe. I started off by explaining the concept of rate limiting and the need for such a mechanism in online services to prevent abuse. I then suggested a token bucket approach. The interviewer asked clarifying questions regarding edge cases, such as what to do when the limit is hit and how to handle concurrent users. We discussed the pros and cons of different strategies like fixed window and leaky bucket algorithms. Overall, it was a positive experience, although I felt that I could have clarified my thought process better during the coding part.
