Your model performs well offline and poorly in production. How do you find out why?
- Tie the answer to modeling, data quality, experimentation, deployment, and business impact so it sounds specific to this role.
- Name your personal contribution without taking credit for the whole team.
- Close with what changed afterward: metric, habit, process, or stakeholder trust.

I would answer with a specific example tied to modeling, data quality, experimentation, deployment, and business impact. The structure should be situation, decision, action, result, and lesson. For a mid Data / AI Expert interview, the answer should include the tradeoff I made, how I communicated it, and the measurable signal that showed whether the work succeeded.
