Interview Prompt

We're validating recorded step logs, each a string of lowercase codes where the rule is that no `a` step may appear once a `b` has occurred. Return whether a given log holds to that order.

Summary

Some rules say every A must come before every B.

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
