Ahead of picking one framework to standardize on for 2026, an analyst is comparing the models in `ml_models` trained that year. Show each framework's average accuracy, highest first.

Summary

One team, one framework. Let the accuracy numbers decide.

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
