Summary

PM interview at Nubank with a product metrics question framed around Uber Lite. Pretty focused session, just the one scenario but it went deep fast.

I went straight to activation and ride completion rates, which felt safe, but the follow-up pushed me on whether I was thinking about the right user segment at all.

Suggested Approach

Start by clarifying the launch's strategic intent—whether it's to test a new market, validate a lean product, or complement existing offerings—then define success across a balanced set of metrics covering adoption, engagement, retention, and operational efficiency. Emphasize that success should be measured against pre-defined targets and tied to learnings for future iterations.

Pro tip: Frame success metrics in the context of Nubank's broader ecosystem—show how the ride-hailing MVP can drive cross-sell, engagement, or data insights for other financial products. Also, set a clear evaluation timeline (e.g., 30/60/90 days) to avoid premature judgments.

1. Clarify strategic objectives

Ask or state the primary goal of the MVP: is it to test demand, enter a new market, or enhance the existing product suite? This shapes which metrics matter most.

2. Define success dimensions

Break success into key areas: user acquisition (e.g., sign-ups, first rides), engagement (e.g., rides per user, frequency), retention (e.g., repeat usage), and operational health (e.g., ride completion rate, wait times).

3. Select leading and lagging indicators

Choose metrics that signal early traction (e.g., activation rate) and long-term viability (e.g., retention, NPS). Ensure they are measurable with available data.

4. Set targets and benchmarks

Establish realistic targets based on industry benchmarks, internal goals, or pilot results. Define what 'good' looks like for each metric.

5. Plan measurement and iteration

Outline how you'll collect data, analyze results, and use insights to decide whether to iterate, pivot, or scale. Include a timeline for evaluation.

Key Points to Mention

  • North Star Metric: e.g., number of completed rides per week, aligned with strategic goal.
  • Activation and engagement metrics: sign-up to first ride conversion, rides per active user.
  • Retention and loyalty: repeat usage rate, cohort retention curves.
  • Operational efficiency: average wait time, ride completion rate, cancellation rate.
  • Customer satisfaction: NPS or CSAT scores from riders and drivers.
  • Learning goals: qualitative feedback, feature usage, and technical performance to inform next steps.
