Interview Process
During my phone screen for the Software Engineer position at Roblox, I was asked about my experience with rate limiting algorithms. The interviewer introduced a scenario where I had to design a system that prevents users from exceeding a certain number of requests per minute. I explained a token bucket approach and how it can be implemented efficiently using data structures.
After discussing the initial design, the interviewer challenged me with edge cases, such as burst traffic and how to handle different user priorities. We had a good back-and-forth discussion about the pros and cons of various approaches, which lasted about 20 minutes. The remaining time was spent on behavioral questions, where I shared my experiences working on team projects and the challenges I faced.
