Interview Process

I had a technical phone screen with Roblox. The interviewer asked me to implement a rate limiter, which is a critical component for managing API request limits. We discussed various algorithms for rate limiting, including token bucket and leaky bucket. I implemented a basic token bucket solution and talked through the pros and cons of different approaches. We also touched on edge cases and performance considerations, like how to handle spikes in requests. Overall, it was a good experience, albeit challenging.
