answer structure

An experience probe that sinks more candidates than any design question, because a vague answer ends the interview early. The four-plane structure that proves you're an operator, not a data scientist with MLOps on the resume.

The experience probe where tool soup fails and one well-told pipeline wins. The context-stack-hardest-problem-outcome structure, the two challenges every real implementation hits, and the before/after numbers that make the story land.
