Summary

Samsung PM interview with a product analytics case about diagnosing a revenue drop on an e-commerce platform. Single question, pretty open-ended, felt like a structured problem-solving exercise more than a behavioral round.

Q1

Online orders on The New Yorker's platform have dropped 30%. How would you diagnose what's going wrong?

I started by trying to segment the drop: is it traffic, conversion, or order completion?

Suggested Approach

Start by clarifying the scope and confirming the metric definition, then systematically segment the drop by time, user cohorts, platform, and funnel stage to isolate the root cause. Prioritize hypotheses using data, and propose a validation plan (e.g., A/B test or deeper analysis) before jumping to solutions.

Pro tip: Always validate the data first—check for tracking errors, seasonality, or external events (e.g., a major news cycle) before assuming a product issue. This shows analytical rigor and prevents wasted effort on false problems.

1. Clarify and Validate

Confirm the metric definition (e.g., what counts as an 'online order'), time period, and data source. Check for instrumentation issues, seasonality, or external factors that could explain the drop.

2. Segment and Localize

Break down the 30% drop by dimensions such as time (sudden vs. gradual), user cohorts (new vs. returning), platform (web vs. mobile), geography, and product category to identify where the drop is concentrated.

3. Analyze the Funnel

Map the purchase funnel (e.g., visit → product view → add to cart → checkout → purchase) and compare conversion rates at each stage to pinpoint where the drop occurs.

4. Form and Prioritize Hypotheses

Generate potential causes (e.g., pricing change, UX issue, competitor launch, technical bug) and prioritize based on data signals and impact.

5. Validate and Recommend

Propose quick validation methods (e.g., A/B test, user research, logs) and outline next steps for remediation or further investigation.

Key Points to Mention

  • Metric definition and data validation to rule out tracking errors
  • Segmentation by time, user type, platform, and geography
  • Funnel analysis to isolate the stage with the biggest drop
  • Hypothesis prioritization using impact and likelihood
  • A/B testing or experimentation to confirm root cause
  • External factors (e.g., seasonality, news events, competitor actions)
