Interview Process

I had a technical phone screening with Roblox. The interviewer started off with some general questions about my background and then moved on to the coding question. The main question was about implementing a rate limiter. Specifically, I was asked to design a class RateLimiter that would allow a certain number of requests in a given timeframe, adhering to specific constraints. I discussed my approach, laying out the design and assumptions, and then proceeded to write the code. The interviewer asked several follow-up questions about edge cases and performance considerations. We also reviewed the code together, optimizing it further based on some feedback.
