Suggested Approach

Choose three apps that you genuinely use and can speak about with insight, ideally showing range in product types. For the chosen app, quickly frame the company's mission and business model, then identify the single KPI that best captures sustainable value creation—balancing user value and business value. Explain why that KPI is the best proxy for long-term success, and how you'd guard against gaming it.

Pro tip: Pick a KPI that is a leading indicator of long-term growth, not a lagging one like revenue. Show you understand trade-offs by mentioning a counter-metric you'd monitor to prevent unintended consequences.

1. Select apps strategically

Choose three apps you know well and that represent different product categories (e.g., utility, social, productivity). Briefly state why you love each, focusing on the user problem they solve.

2. Pick one and set context

Select the app where you can most clearly articulate the business model and user value. In one sentence, state its core mission and how it makes money.

3. Define the single most important KPI

Identify one KPI that best measures the health of the product's core value exchange. Explain why it's the best proxy for long-term success, linking it to both user and business outcomes.

4. Justify and defend

Explain why this KPI is superior to alternatives, and how it would guide decisions. Mention potential pitfalls and a counter-metric to ensure balanced growth.

Key Points to Mention

  • The KPI should reflect the core value exchange between users and the business.
  • Distinguish between leading and lagging indicators; prefer leading indicators for proactive management.
  • Consider the KPI's alignment with the company's mission and long-term strategy.
  • Acknowledge trade-offs and mention a counter-metric to prevent gaming or short-termism.
  • Show awareness of how the KPI would be measured and its sensitivity to product changes.
  • Demonstrate product sense by connecting the KPI to user behavior and business outcomes.
