Interview Prompt

Implement a RateLimiter(max_requests, window_seconds). Each allow(timestamp) call returns True when the number of requests already recorded with timestamps in (timestamp - window_seconds, timestamp] is strictly less than max_requests, then records this timestamp. Returns False otherwise. The test harness passes parallel lists of calls and timestamps and expects a parallel list of booleans.

Summary

Too many requests in too short a timeframe. Throttle it.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your python solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
