Interview Prompt

A real-time monitoring service tracks events and counts how many occurred in the last 5 minutes (300 seconds). Design a hit counter class with a hit method that records a timestamp and a get_hits method that returns the count of hits within the last 300 seconds of a given timestamp.

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
