Metrics question
What metric framework would you use to determine whether OpenAI’s agent infrastructure is actually helping developers build faster, run more reliable agents, and achieve better end-user outcomes? Which metrics would you treat as leading indicators, which as outcome metrics, and how would you avoid being misled by adoption vanity metrics?

What this question tests
Tests building a layered metric framework for developer infrastructure that connects developer adoption to real end-user outcomes, without being fooled by usage volume alone.
How to approach it
- Separate three layers: developer-facing, does infra help developers build faster, agent-facing, does it run more reliably, and end-user-facing, do people get better outcomes.
- Pick leading indicators: time-to-first-successful-agent-call, percent of API calls passing internal evals, and error or retry rate per agent run.
- Pick outcome metrics: agent task completion rate, production-deployment rate of prototypes, and downstream end-user satisfaction or task success where measurable.
- Flag vanity metrics to avoid, like total API calls or signups, since they rise even if agents fail in production.
- Cross-check leading and outcome metrics against each other, for example rising call volume with falling completion rate signals a real problem, not growth.
What a strong answer includes
- Builds an explicit three-layer tree, developer, agent, end user, instead of one flat metric list.
- Names specific leading indicators, time-to-first-call and eval pass rate, that predict production success before it happens.
- Explicitly calls out API call volume as a vanity metric that can rise while quality falls.
- Proposes a guardrail pairing, like completion rate against call volume, to catch misleading growth.
Common mistakes
- Treating total API usage or signups as success without a quality or completion metric.
- Picking metrics that only measure developer sentiment, not what actually happens in production.
- Building a long metric list with no leading versus lagging structure to act on.
Likely follow-up questions
- Which one metric would you put on an executive dashboard?
- How would you know if a leading indicator stopped predicting the outcome?
