Interview Prompt

A document editor lines up the original and edited version of a sentence so a reviewer can see what changed. Given the two versions as `sentence_a` and `sentence_b`, return the words that appear in only one of them.

Summary

Two versions of the same line. Surface only what changed.

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
