AI eval design

AI eval design is the methodology for measuring whether an LLM-backed feature is working — golden sets, regression checks, online proxy metrics, and human review.

Why interviewers test it

Eval design separates AI PMs from PMs who 'use AI'. Interviewers test whether you can describe a real evaluation pipeline, not just say 'we'd benchmark it'.
