Interview Process

I had a technical phone screen with Roblox for a Software Engineer position. The interviewer started with general introductions and background about the team and the company. We then moved on to the coding problem.

The problem was about implementing a rate limiter, which required allowing a certain number of requests in a given timeframe and blocking any excess requests. I explained my thought process and came up with a solution.

I discussed different strategies such as using a sliding window or a token bucket approach, ultimately deciding on a simple token bucket mechanism for clarity and simplicity. I wrote the code step by step while explaining my logic.

After the coding portion, the interviewer asked a few behavioral questions about my previous experience and how I handled challenges in a team environment. Overall, it was a good experience, but I felt that I could have optimized my solution further if I had more time.
