Explanation
Hint: Identify the requirement first, then choose the approach that addresses the main constraints, trade-offs, failure modes, security, cost, and verification.
Correct 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.
Why the alternatives are weaker:
- Using one generic accuracy metric
- No lineage
- Promoting based only on offline performance
What the interviewer is testing
- Evaluation design
- Artifact lineage
- Release safety
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?
