Interview Process

During my phone interview with Roblox for a Software Engineer position, the interviewer focused primarily on a coding question related to rate limiting. The question required me to design a system that could handle requests without exceeding a specified limit. I explained my approach to implementing a token bucket algorithm, detailing how I would manage the tokens and handle excess requests. The interviewer asked several follow-up questions, including how to deal with bursts of traffic and the potential challenges of distributed systems.

After the coding portion, we transitioned into behavioral questions where I was asked about my past experiences, challenges I’ve faced in previous roles, and how I approach problem-solving in a team setting. Overall, the interview lasted about 30 minutes, and I felt it went well although I didn’t receive an immediate outcome. I am currently waiting for their response.
