Summary

Google PM interview, product sense round. One question, mobile app focus, pretty open-ended. Left feeling like I could've pushed my answer a lot further than I did.

Questions Asked (1)

Q1

Pick a mobile app. How would you increase user engagement by 100x?

I picked a messaging app thinking it'd be easier to brainstorm around, but the 100x framing kind of broke my usual approach.

Suggested Approach

Choose a well-known app with clear engagement metrics, then define what '100x' means in terms of a specific metric (e.g., DAU, session length). Structure your answer by first diagnosing current engagement drivers and friction points, then proposing a mix of product changes, growth loops, and measurement strategies to achieve the 100x goal.

Pro tip: Acknowledge that 100x is an ambitious, likely unrealistic target, and instead focus on the multiplicative levers (e.g., viral loops, network effects) that could theoretically drive exponential growth. Show you understand the difference between linear and exponential growth.

1. Select the App and Define Engagement

Pick a familiar app (e.g., Google Maps, Instagram) and specify the key engagement metric you aim to increase (e.g., daily active users, sessions per user, time spent).

2. Diagnose Current Engagement

Analyze the current user journey, identify core value propositions, and pinpoint friction points or unmet needs that limit engagement.

3. Identify Levers for 100x Growth

Brainstorm high-impact changes across product features, user experience, incentives, and virality that could drive exponential increases.

4. Prioritize and Propose Solutions

Evaluate ideas based on impact, feasibility, and alignment with company goals; select a few key initiatives to focus on.

5. Define Metrics and Iterate

Outline how you would measure success, run experiments, and iterate to validate and scale the most promising solutions.

Key Points to Mention

  • Clearly define the engagement metric and why it matters for the chosen app.
  • Consider both acquisition and retention aspects of engagement.
  • Leverage network effects, virality, or personalization to drive exponential growth.
  • Use data to identify high-impact opportunities and prioritize.
  • Propose A/B testing and iterative improvements to validate ideas.
  • Acknowledge potential trade-offs (e.g., user experience vs. growth tactics).
