What gates should a model pass before it is promoted to production?

Interview Question

What the interviewer is testing

Evaluation design
Artifact lineage
Release safety

Real-World Sample Answer

I would approach “What gates should a model pass before it is promoted to production?” by clarifying the requirements first, then using these considerations: in a real interview, i would not jump straight to a technology choice. for “what gates should a model pass before it is promoted to production?”, i would first define task-specific quality thresholds. then i would track data and model artifacts and compare against the current production model. i would also check safety, latency, and resource constraints. finally, i would define promotion and rollback conditions. i would make the assumptions explicit and explain what evidence or production signals would make me revisit the decision.. I would state my assumptions and defend the trade-offs rather than presenting the choice as universally correct.

What a Strong Answer Should Cover

In a real interview, I would not jump straight to a technology choice. For “What gates should a model pass before it is promoted to production?”, I would first define task-specific quality thresholds. Then I would track data and model artifacts and compare against the current production model. I would also check safety, latency, and resource constraints. Finally, I would define promotion and rollback conditions. I would make the assumptions explicit and explain what evidence or production signals would make me revisit the decision.

Common Mistakes

Using one generic accuracy metric
No lineage
Promoting based only on offline performance

Interviewer Follow-ups

What assumptions would you clarify before committing to the design?
What changes if the scale, reliability target, security requirement, or budget changes?
What is the biggest failure mode in your proposed approach?
