Summary

Lyft PM interview with a classic metrics diagnostic question. Pretty standard case format but the specificity of the number (45%) made me second-guess myself more than I should have.

Questions Asked (1)

Q1

Ride orders on Lyft dropped by 45%. How would you diagnose what's going on?

I started with clarifying questions about the timeframe and whether it was across all markets or localized, which felt right.

Suggested Approach

Start by clarifying the scope and timeframe of the 45% drop, then systematically break down the metric into its components (e.g., by geography, user segment, ride type, and funnel stage) to isolate the cause. Prioritize hypotheses based on internal vs. external factors and validate with data before proposing solutions.

Pro tip: Demonstrate a hypothesis-driven approach by ranking potential causes by likelihood and impact, and mention how you would use A/B tests or cohort analysis to confirm the root cause. Also, consider both supply and demand sides, as ride orders depend on driver availability and rider demand.

1. Clarify and Scope

Ask clarifying questions to understand the metric definition, timeframe, and whether the drop is global or segment-specific. Confirm if it's a sudden or gradual decline and if it's consistent across platforms.

2. Segment the Data

Break down the 45% drop by dimensions such as geography, time, user demographics, ride type, and acquisition channel. Use funnel analysis to see where the drop-off occurs (e.g., app opens, ride requests, completed rides).

3. Generate Hypotheses

Brainstorm potential internal and external causes: seasonality, competitor actions, pricing changes, product bugs, marketing campaigns, driver supply issues, or macroeconomic factors. Prioritize by likelihood and impact.

4. Validate with Data

Use data analysis to test each hypothesis: compare cohorts, run correlation analyses, check for anomalies in logs, and review external benchmarks. Consider A/B tests if applicable.

5. Synthesize and Recommend

Summarize findings, identify the most probable root cause(s), and propose next steps for mitigation or further investigation. Outline how you would monitor the metric going forward.

Key Points to Mention

  • Clarify the metric: Is 'ride orders' the same as completed rides? Does it include cancellations?
  • Segment by geography, user cohort, ride type, and time to localize the drop.
  • Consider both supply-side (driver availability, incentives) and demand-side (pricing, competition, seasonality) factors.
  • Use funnel analysis to pinpoint where users drop off (e.g., request to match, match to pickup).
  • Check for internal changes: product updates, pricing algorithms, marketing campaigns, or bugs.
  • Evaluate external factors: competitor promotions, regulatory changes, economic trends, or weather events.
