Interview Process

I had a technical phone interview with Roblox for a Software Engineer position. The interview started with some behavioral questions about my experience and projects. We then moved on to the technical part, where I was asked to discuss how to design a system that limits the rate of requests from users.

After discussing the theory, I was asked to code the rate limiter in real-time. I implemented the token bucket solution in Python and explained my thought process. The interviewer was engaged and asked follow-up questions to challenge my solution, focusing on edge cases and efficiency. Overall, the interview lasted around 24 minutes.
