“How would you improve WhatsApp?”
If you’ve interviewed for a PM role at Meta or any major tech company, you’ve likely faced this question - or one very similar to it. It’s deceptively simple, deliberately open-ended, and designed to reveal how you think about products, users, and trade-offs.
Today, I’m walking you through exactly how I’d answer this question using the PQ-GUP-SEMS framework. This isn’t just theory - it’s a real, interview-ready response that demonstrates structured thinking, user empathy, and business acumen.
Let’s dive in.
How To Answer Product Improvement Questions?
Here’s a proven nine-step framework for answering any product improvement question.
0. Keywords - Pay attention to the keywords in the question.
1. P - Product: Describe what the product does and who it serves.
2. Q – Questions: Ask clarifying questions to narrow the scope.
3. G – Goal: Define the business or user goal you’re improving.
4. U – Users: Identify user segments and pick one to focus on.
5. P – Pain Points: List key pain points for that segment.
6. S – Solutions: Brainstorm possible improvements.
7. E – Evaluate: Prioritize solutions and discuss trade-offs.
8. M – Metrics: Define success metrics.
9. S – Summarize: Recap your reasoning clearly.
Use the mnemonic PQ-GUP-SEMS to remember the sequence.
Step 0: Listen for Keywords
The question is: “How would you improve WhatsApp?”
Key observations:
“Improve” is ambiguous - could mean engagement, retention, revenue, features, or user experience
“WhatsApp” - the entire platform, not a specific feature
No specific user segment mentioned
No geographic or platform constraints given
I’d write this down to stay focused throughout my answer.
Step 1: Describe the Product
WhatsApp is a cross-platform messaging application that enables users to send text messages, voice messages, make voice and video calls, and share media files over the internet. It serves over 2 billion users globally, with particularly strong adoption in markets like India, Brazil, and across Europe and Asia.
The product is designed for personal communication—connecting friends, families, and increasingly, small businesses with their customers. Users engage with WhatsApp multiple times daily for quick, reliable, and private communication. The core pain point WhatsApp solves is enabling free, instant communication across borders without SMS fees, while maintaining end-to-end encryption for privacy.
WhatsApp’s key differentiators are its simplicity, reliability, and privacy-first approach. Unlike other social platforms, it focuses purely on communication rather than content discovery or social networking.
Confirm with interviewer: “Does this align with your understanding of WhatsApp?”
Step 2: Ask Clarifying Questions to trim down the scope of the question
Before proceeding, I’d ask:
Q1: When you mention ‘improve,’ what aspect should I focus on? Are we looking at:
User engagement and retention?
Revenue generation?
New user acquisition?
Feature expansion?
Or would you like me to choose based on what I think is most strategic?
Q2: Are there any specific user segments or geographic markets I should prioritize, or should I consider the global user base?
Q3: Should I focus on a particular platform—mobile app, web, or desktop—or can I think broadly across all platforms?
Q4: Are there any constraints I should be aware of, such as maintaining WhatsApp’s privacy-first approach or its simple user interface?
→ Interviewer response (assumed): “Focus on improving engagement. You can choose the user segment and should maintain WhatsApp’s core values of privacy and simplicity.”
Step 3: Define the Goal you want to achieve.
Given the direction to focus on engagement, I’ll aim to increase daily active usage and the depth of engagement for WhatsApp users. This is strategically important because:
Higher engagement drives network effects - More active users make the platform more valuable for everyone
Engagement supports monetization - Through WhatsApp Business and future revenue streams
Retention follows engagement - Deeply engaged users are less likely to churn
Competitive positioning - With competition from Telegram, Signal, and iMessage, maintaining high engagement keeps users loyal
I’ll measure success through metrics like
messages sent per user per day,
session frequency,
session duration,
and, feature adoption rates.
Step 4: Identify User Segments for WhatsApp
