Interview Process
The interview started with basic background questions about my experience and reason for applying. After that, the interviewer introduced the problem: ‘Rate Limiter’. The task was to implement a rate limiting algorithm that controls the rate at which requests are processed.
I explained my thought process about how to structure the solution and mentioned different approaches like token bucket and leaky bucket algorithms. The interviewer asked me to code the solution in real-time, which I did in Python.
After coding, I discussed the time and space complexity. The interviewer then asked some follow-up questions regarding how to handle edge cases such as burst requests and how to persist the state if the system crashes. Finally, we touched upon how the rate limiter could be scaled in a distributed system context. Overall, it was a positive experience and the interviewer was very supportive throughout the process.
