Interview Round: Technical Screen
You are the Product Manager for an e-commerce marketplace. You notice a rise in negative comments and reviews from users.
How would you investigate the issue, prioritize the response, work with cross-functional teams, and decide what actions to take?
### Constraints & Assumptions
- Negative comments may come from app reviews, on-site reviews, support tickets, social media, buyers, sellers, or delivery partners.
- Do not assume the root cause before segmenting the problem.
- Balance customer trust, marketplace integrity, seller fairness, operational feasibility, legal/comms risk, and business impact.
- Include short-term mitigation and long-term prevention.
### Clarifying Questions to Ask
- Where are the negative comments appearing, and which users are affected?
- Did the rise begin after a product launch, policy change, logistics issue, pricing change, or seasonal event?
- Are comments about product quality, delivery, checkout, returns, seller behavior, search relevance, pricing, or trust and safety?
- How severe is the issue in volume, revenue impact, retention risk, and public visibility?
### Part 1 - Diagnose The Problem
How would you investigate the rise in negative comments?
#### What This Part Should Cover
- Segmentation by source, user type, topic, product area, geography, cohort, device, seller, and time.
- Quantitative analysis of volume, trend, affected GMV/orders, refund rate, contact rate, and retention risk.
- Qualitative review of comments, support tickets, user sessions, and seller/operator input.
### Part 2 - Prioritize The Response
How would you decide what to handle first?
#### What This Part Should Cover
- A severity framework such as reach, impact, confidence, urgency, reversibility, and trust risk.
- Distinction between urgent incidents, high-volume friction, and lower-priority cosmetic complaints.
- Clear guardrails for customer safety, payment issues, fraud, legal exposure, and marketplace trust.
### Part 3 - Work Cross-Functionally
Which teams would you involve, and how would you coordinate action?
#### What This Part Should Cover
- Engineering, analytics, customer support, operations/fulfillment, seller teams, trust and safety, legal/comms, design, and leadership where appropriate.
- One source of truth for what is known, owners, timelines, decisions, and customer communication.
- A plan for both immediate mitigation and root-cause fixes.
### Part 4 - Define Actions And Metrics
What actions would you take, and how would you know whether they worked?
#### What This Part Should Cover
- Short-term actions such as pausing a broken experiment, fixing a bug, improving communication, issuing credits/refunds, or escalating abusive/fraudulent content.
- Long-term fixes based on root cause, such as catalog quality, delivery reliability, returns flow, search relevance, seller enforcement, or product education.
- Metrics for negative-comment rate, CSAT/NPS, refunds, support contacts, repeat purchase, seller health, moderation accuracy, and issue-specific outcomes.
### What a Strong Answer Covers
- Does not jump to one solution before diagnosing.
