Interview Process
The interview started with a brief introduction about my background. Then the interviewer moved on to the technical portion. The main problem was related to rate limiting: how would you implement a rate limiter? We discussed several approaches, including token bucket and leaky bucket algorithms. I explained how token bucket can allow bursts of requests while maintaining an average rate. The interviewer asked about the trade-offs between the two algorithms, which I answered confidently.
After discussing the algorithms, we moved to a coding exercise where I had to implement the rate limiter in the language of my choice (I chose Python). I described my thought process as I coded, and the interviewer provided feedback throughout. Finally, we wrapped up with a few behavioral questions, asking about how I handle tight deadlines and work in teams. Overall, it was a positive experience!
