Interview Prompt
The lifecycle marketer building a win-back list wants the non-active accounts in `users` that are too incomplete to use, with no email to send to or no age bracket to segment by. Return each such user with the year they signed up.
Summary
No email on file. No recent activity. Something smells off.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your SQL against a real database
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
