Interview Prompt

Return each message's ID and its word count from `chat_msgs`, for an analyst profiling how wordy the chat is who treats every space in the content as a divider between words.

Summary

Every pause between words is a vote for length. Count them.

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 SQL against a real database
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
