Interview Prompt

We're screening numeric IDs against a self-referential property: an ID passes when each of its digits, raised to the power of how many digits the ID has, sums back to the ID itself. Return whether a given `n` passes.

Summary

Some numbers describe themselves perfectly.

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
