Interview Process

The interview consisted of a phone screen with the recruiter followed by a technical interview. During the technical interview, I was asked about rate limiting algorithms and how to implement them efficiently. The interviewer presented a scenario where I had to design a rate limiter that could throttle requests based on configurable limits from different users. We discussed various algorithms including token bucket and leaky bucket, along with their pros and cons. After the technical questions, I had a chance to ask some questions about the team and culture at Roblox. Overall, the experience was positive, though I felt challenged by the technical depth of the questions.
