Interview Prompt

We stamp each `seed` string with a short token: its SHA-256 hex digest, cut down to the first `length` characters.

Summary

One input, one irreversible output - the foundation of every secret.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your Python against test cases
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
