Interview Process
I had a phone screen with Roblox where I was asked about a Rate Limiter problem. The interviewer wanted to understand how I would implement a rate limiter for API calls to ensure that users do not exceed a specific number of requests in a time frame. I explained the concept of a token bucket or leaky bucket algorithm and walked through my thought process on how to maintain the count of requests and implement the logic for the rate limiting. I also discussed handling edge cases and scaling the solution. Towards the end, the interviewer asked a few behavioral questions to assess my fit within the team culture. Overall, it was a standard technical phone screen with a mix of coding and behavioral questions.
