Interview Prompt
A reviewer auditing the live ML fleet wants one number: how many models in `ml_models` have at least one deployed version with accuracy of 0.9 or better?
Summary
A model is not a model until it stops learning and starts earning.
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
