Interview Process
I had a phone screen interview with Roblox. The interviewer was very friendly and started off with some introductory questions. After that, he asked me to solve a coding problem involving rate limiting.
The problem was about designing a rate limiter for an API. The challenge was to ensure that a user couldn’t exceed a set number of requests in a certain time frame. I first discussed the problem, explaining how I would approach it using leaky bucket or token bucket algorithms.
Next, I wrote out the code, ensuring to handle edge cases as well as rate limiting logic. The interviewer asked a few follow-up questions regarding my implementation choices and edge cases, which I addressed. Overall, it was a positive experience, and I’m excited to see where it goes from here!
