What is RCA?
Root Cause Analysis (RCA) is like detective work for business problems. If fewer people are using Netflix or Paytm, RCA helps identify why. In interviews, you may be asked, “Why has YouTube’s viewership dropped?”—your task is to think logically and use data to find the cause.
Why Do Interviewers Ask RCA Questions?
Interviewers want to assess your analytical skills. They test how well you break down problems, structure your thinking, and communicate solutions. RCA questions evaluate whether you can diagnose issues like a decline in Paytm transactions or Netflix subscriptions.
Four Key Skills for RCA
1. Product Sense – Understanding the product at a high level and diving into details, like zooming from a satellite view down to street level.
2. Problem Solving – Identifying the root cause of an issue, similar to how a detective uncovers clues.
3. Structured Thinking & Communication – Organizing thoughts logically and verifying whether the problem is real before solving it.
4. Domain Knowledge – Having relevant industry expertise, which acts as a toolkit to analyze issues effectively.
RCA Approach in Interviews
Understanding the Problem
• Clarify the metrics – What does “drop” mean? Is it a decline in users, transactions, or revenue?
• Determine the trend – Is the drop sudden, gradual, or seasonal?
• Segment the impact – Does the decline affect specific locations, devices, or user types?
Exploring External Factors
• Market Conditions – Regulatory changes, economic shifts, or new competitors.
• Social & Industry Trends – Negative PR, social media sentiment, or competitor campaigns.
• Events & Seasonality – Festival seasons, policy updates, or external disruptions.
Investigating Internal Factors
• User Experience & Journey – Any changes in app flow, navigation, or checkout process?
• Technical & Product Issues – Bugs, performance issues, or pricing adjustments.
• Platform-Specific Insights – Are issues more prevalent on iOS, Android, or web?
Effective RCA Execution
1. Break the problem into smaller parts – Start broad, then drill down.
2. Reiterate the problem statement – Confirm understanding before solving.
3. Ask structured scoping questions – Geography, user segments, affected business areas, and exact impact.
4. Take notes & involve the interviewer – Document responses for reference and maintain a two-way conversation.
5. Prioritize problem areas – If external factors don’t explain the issue, move to internal causes.
6. Use the User Journey Approach – Analyze the drop at different stages (onboarding, engagement, retention) to identify weak points.
Final Tips for RCA Interviews
• Stay confident & structured – Avoid jumping to conclusions.
• Engage the interviewer – Ask questions to clarify assumptions.
• Don’t hesitate to iterate – The interviewer may test your adaptability by changing the scenario.
By mastering RCA, you can approach problem-solving like a pro, whether in an interview or real-world product management scenarios.
