What this question tests
Tests incident triage for a B2B revenue drop: ruling out measurement error, isolating account concentration, and structuring a fast, communicated response.
How to approach it
- Clarify the metric: new revenue, renewals, or active subscriptions, and over what window, since the response differs by definition.
- Triage first for a data or billing pipeline error (broken invoicing job, payment processor outage) before assuming real churn.
- Segment by account size: in B2B, a 20% drop could be one or two large enterprise accounts churning, not broad decline.
- Check external causes: a price change, a competitor offer, an outage or security incident, or enterprise IT budget pull-back.
- Check internal causes: a product change, a billing bug undercharging accounts, or a broken renewal process.
- Stand up a cross-functional incident channel same-day and give leadership a preliminary update within 24-48 hours.
What a strong answer includes
- Checks for a billing pipeline bug before assuming real churn, a step experienced PMs specifically look for.
- Segments by account size immediately, since B2B revenue concentrates in a few large accounts unlike consumer metrics.
- Proposes a concrete incident process (cross-functional channel, fast preliminary update) rather than just listing hypotheses.
- Names realistic causes (price change, security incident, IT budget cuts) grounded in real enterprise spend behavior.
Common mistakes
- Assuming real churn without first ruling out a measurement or billing error.
- Treating the drop as broad-based without checking account concentration.
- No urgency or communication plan, just a static list of causes.
Likely follow-up questions
- How would you communicate this before you have a root cause?
- How would your approach differ for a consumer product?
- What would you do differently if it were one lost enterprise account?
