Interview Process
I had a phone screen interview with Roblox where I was asked about the rate limiting algorithm. The interviewer first asked me to explain how rate limiting works. I shared the concept of allowing a specific number of requests within a time window, and how it prevents abuse of APIs. Then I was asked to implement a basic rate limiter in code. The interviewer was looking for a simple approach to manage tracking of request timestamps and to return whether a request should be allowed or denied. Overall, it was a great experience, and the interviewer was very friendly and receptive to my thought process.
