Summary

Google PM interview with a single product design question about building a birthday celebration app. Pretty open-ended and I wasn't totally sure how deep they wanted me to go on the social vs. utility angle.

I went straight to user segments, which in hindsight was fine but I probably spent too long on personas before getting to the actual product.

Suggested Approach

Start by clarifying the goal and scope of the app, then segment users and identify their core needs around birthdays. Prioritize features that deliver unique value, and outline a monetization strategy that aligns with Google's ecosystem and user privacy expectations.

Pro tip: Emphasize how the app leverages Google's strengths (e.g., Calendar, Contacts, AI) to create a seamless and intelligent experience, while being mindful of privacy and data security.

1. Clarify Goal & Scope

Ask clarifying questions to understand the app's primary objective (e.g., social connection, reminders, gift suggestions) and target audience (e.g., individuals, groups, businesses).

2. User Segmentation & Needs

Identify key user segments (e.g., busy professionals, social butterflies, family organizers) and their pain points around birthdays, such as forgetting dates or finding gifts.

3. Feature Ideation & Prioritization

Brainstorm features that address user needs, such as smart reminders, gift recommendations, group cards, and social sharing. Prioritize based on impact and feasibility.

4. Monetization & Metrics

Propose monetization strategies (e.g., premium features, affiliate partnerships, ads) and define success metrics (e.g., DAU, retention, conversion rates).

5. Integration & Differentiation

Explain how the app integrates with Google's ecosystem (Calendar, Contacts, Assistant) and what makes it unique compared to competitors like Facebook or Evite.

Key Points to Mention

  • Leveraging Google's data and AI for smart reminders and personalized suggestions
  • Privacy and data security considerations, especially around contacts and calendar access
  • Potential monetization through premium features (e.g., advanced customization, ad-free) or affiliate partnerships (e.g., gift shops)
  • Social features like collaborative cards and event planning to drive engagement
  • Metrics for success: user acquisition, retention, engagement, and monetization
  • Competitive landscape and differentiation from existing apps
