Interview Process

I had a phone screen interview with Roblox for a Software Engineer position. The interview lasted about 12 minutes. The interviewer asked me to solve a Rate Limiter problem, which involved implementing a function that limits the number of requests sent to an API over a certain period.

Technical Questions

  1. Rate Limiter (Data Structures, Algorithm)

Tips & Insights

I discussed potential solutions like token bucket algorithms and how to handle edge cases such as burst requests. After explaining my solution, I went through the time and space complexities compared to other options. Overall, I think the interview went well, but I’m unsure about their decision-making process.
