Metrics question

You're the PM for Google Cloud storage. How would you measure success?

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Ability to define success metrics for an infrastructure product where reliability and cost matter as much as growth.

Clarify Google Cloud Storage's value proposition: reliable, scalable, cost-effective storage for developers and enterprises.
Define a growth metric: total storage under management and active projects using the service, reflecting adoption.
Define a reliability metric: uptime and data durability, since any data loss is catastrophic for a storage product's trust.
Define a cost-efficiency metric: cost per GB served to the customer relative to competitors, since storage is price-sensitive at scale.
Define a developer experience metric: API latency and support ticket volume related to storage issues.
Set a guardrail: churn rate among enterprise customers, since storage switching costs are high, so churn signals a serious problem.

Leads with durability and uptime as non-negotiable guardrails, correctly identifying reliability as more important than growth for infrastructure.
Names cost per GB explicitly, since storage is a commodity market where price competitiveness drives adoption.
Gives an illustrative benchmark, e.g. 99.999% durability with sub-100ms API latency, marked as an assumption.
Flags enterprise churn as a lagging but critical signal given high switching costs mask problems until it's too late.

Treating this like a consumer product and focusing only on growth metrics.
Ignoring reliability and durability, which are existential for a storage product's trust.
