Interview Process
I had a phone screen with Roblox for a Software Engineer position. I started with a brief introduction about myself and my experiences. The interviewer then asked me a technical question related to rate limiting, which involved designing a system to limit the number of requests a user can make to an API within a specific time frame. They were particularly interested in how I would structure the solution, what data structures I would use, and how I would handle edge cases. We discussed different strategies like token bucket and leaky bucket algorithms. I provided a solution that included a Redis implementation for storing the request timestamps, ensuring the system could scale while remaining efficient. After that, the interviewer asked a couple of behavioral questions to assess my soft skills. Overall, the experience was quite engaging, and I felt I managed to convey my thought process clearly. However, I am still awaiting their final decision on the interview outcome.
Technical Questions
- Rate Limiter (System Design, API)
Tips & Insights
- Be prepared to discuss system design concepts in detail, especially regarding scalability and efficiency.
- Familiarize yourself with common algorithms used in rate limiting, such as token bucket and leaky bucket.
- Clearly articulate your thought process during problem-solving, as communication is key in technical interviews.
