Interview Process

The interview for the Software Engineer position at Roblox involved solving a Rate Limiter problem. The challenge required implementing a function to limit the number of requests a user can make to an API within a defined time frame. The interviewer focused on performance optimizations and edge cases. After discussing the basic algorithm, I demonstrated my thought process on efficiently handling requests while ensuring users did not exceed their rate limit.

The technical discussion lasted about 30 minutes and included a code review of the solution I provided. The interviewer asked several probing questions about data structures and performance optimization techniques. Additionally, there was a behavioral aspect where the interviewer inquired about my previous experiences and my approach to problem-solving in team settings. Overall, the interview felt comprehensive and challenging, reflecting the expectations at Roblox.
