Interview Process

I had a technical phone screen for a software engineering position at Roblox. The interviewer asked several questions related to systems design and algorithms. One of the main questions was about implementing a Rate Limiter. I explained the Leaky Bucket and Token Bucket algorithms, providing a clear explanation of how they work and their use cases. After discussing the algorithms, we moved on to coding. I wrote a function to implement a basic rate limiter. We went through the edge cases, and the interviewer provided helpful feedback on my approach and optimization strategies. Overall, it was a good experience, and I felt confident about my performance. I am now waiting for the feedback from the interview.
