Interview Process

This was a phone screen for a Software Engineer position at Roblox. The interviewer was very friendly and made me feel relaxed. The focus of the interview was an algorithm question regarding rate limiting, which involved designing a system that could handle a high volume of traffic while complying with certain API limits.

I was asked to define the problem first and then suggested a few approaches on how to handle it. The interviewer prompted me with questions to refine my solution further, such as how I would handle edge cases and the efficiency of my implementation. I provided a potential data structure I thought would be effective and walked through the implementation details. Overall, it was a positive experience and I felt I communicated my thoughts clearly.
