Interview Prompt
`ml_models` holds one row per trained model version, stamped with the moment training finished and the accuracy it scored against a 0.95 target. Every scored run finished from the start of 2026 through the April 4 freeze belongs in one of ten tenths by how far it lands from the target.
Summary
Most models are fine. The bottom 10% are not.
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
