Interview Process
I had a technical phone screen interview with Roblox. The interviewer focused on designing a system for rate limiting, specifically how to control the number of requests a user can make to a server over time. We discussed different algorithms for rate limiting, such as the token bucket algorithm and the leaky bucket algorithm. I was asked to describe their trade-offs and which one I would choose based on certain scenarios. Additionally, we covered how to handle edge cases like bursts of traffic and how to maintain state across distributed systems. Overall, it was a technical deep dive into system design with an emphasis on scalability and performance considerations. The interviewer seemed pleased with my answers, and I left with a positive feeling about the conversation.
