Interview Process

During my interview at Roblox for a Software Engineer position, I encountered a technical question regarding the design of a rate limiter for an API. The interviewer provided a scenario where I had to explain my thought process while considering constraints such as time windows and request limits. The interview lasted about 25 minutes, during which I implemented the logic in real-time while discussing each part with the interviewer. I asked clarifying questions to better understand the requirements, which seemed to impress the interviewer. After implementing my solution, I walked through the code and explained how it would work in a production environment, detailing points of failure and potential improvements.
