Interview Process

I had a technical phone screen with Roblox for a Software Engineer position. The interview lasted for about 35 minutes. The interviewer asked me to implement a rate limiter as part of the coding exercise. The problem required me to ensure that no more than a certain number of requests could be processed in a given time window.

During the interview, I discussed my approach, including using a sliding window technique to manage the count of requests over time. I also talked about potential edge cases and how to effectively handle them. After the coding part, the interviewer switched gears to behavioral questions, asking about my previous projects and how I handle team dynamics. Overall, I felt the interview went well, and I was able to provide thoughtful answers to the questions posed. The interviewer was professional and gave me a chance to explain my thought process thoroughly.
