Interview Prompt

Our observability toolkit needs a non-invasive way to measure function execution times. Write a function called make_timed that wraps any function to print elapsed time after each call as 'Elapsed: X.XXXXs'. The wrapper must handle any combination of positional and keyword arguments.

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
