Author's notes

I started by trying to define what engagement even means for a messaging app, which felt like the right move but I probably spent too long on it.

Suggested Approach

Start by clarifying the goal of increasing engagement—define what engagement means for WhatsApp (e.g., daily active usage, messages sent, time spent) and identify the target user segment. Then, structure your answer around a hypothesis-driven approach: diagnose current engagement, prioritize opportunities based on impact and effort, propose a solution, and define success metrics. Finally, emphasize the importance of experimentation and iteration.

Pro tip: Show that you understand WhatsApp's core value proposition—private, reliable messaging—and that any engagement feature must not compromise user trust or the simple user experience. Also, mention that you would leverage WhatsApp's unique assets like end-to-end encryption, status, and groups to drive engagement without being intrusive.

1. Clarify and Define Engagement

Ask clarifying questions to understand what 'engagement' means for WhatsApp (e.g., frequency of use, messages sent, time spent) and which user segment to focus on (new users, casual users, power users).

2. Diagnose Current State

Analyze existing data to identify engagement patterns, drop-off points, and user segments with low engagement. Use metrics like DAU/MAU, retention, and feature adoption.

3. Identify Opportunities

Brainstorm potential areas to improve engagement, such as onboarding, status, groups, business messaging, or new features. Prioritize based on impact, effort, and alignment with WhatsApp's principles.

4. Propose and Prioritize Solutions

Select one or two high-potential ideas, detail how they would work, and explain how they would increase engagement. Consider potential risks and trade-offs.

5. Define Success Metrics and Experiment

Outline how you would measure success (e.g., increase in messages sent per user, DAU) and describe a plan to test the solution via A/B testing or pilot, with clear rollback criteria.

Key Points to Mention

  • WhatsApp's core value proposition: simple, private, reliable messaging—any engagement feature must not compromise this.
  • Leveraging existing features like Status, Groups, and WhatsApp Business to drive engagement.
  • The importance of user segmentation (e.g., new vs. existing users, high vs. low engagement) to tailor strategies.
  • Using data to identify engagement gaps and opportunities (e.g., funnel analysis, cohort analysis).
  • Prioritization frameworks like RICE or Impact/Effort to choose the right feature.
  • Defining clear success metrics (e.g., DAU/MAU, messages per user, retention) and a plan for A/B testing.
