Interview Process
I had a phone screen with a recruiter from Roblox. The recruiter was very nice and explained the interview process clearly. The technical part focused on a rate limiter problem, a common scenario in distributed systems. The interviewer asked me to design a rate limiter that could limit the number of requests from a user to a specific endpoint.
I started off by discussing the requirements and potential edge cases. After that, I wrote some pseudocode to illustrate the logic I would use to implement the rate limiter. The interviewer probed me on how I would handle bursts of traffic and what kind of data structures would be optimal for this problem. Overall, it was a challenging but enjoyable interview.
