Summary

Google PM interview, product design question. Pretty open-ended and I kept second-guessing whether I was going broad enough or just spinning my wheels.

Suggested Approach

Start by clarifying the goal and scope of the birthday app, then segment users and identify their key needs. Prioritize features based on impact and feasibility, and outline a phased roadmap with success metrics.

Pro tip: Anchor your answer in a clear product vision and tie every feature back to a specific user need and measurable outcome; this shows strategic thinking and avoids a feature-list trap.

1. Clarify the Goal and Scope

Ask clarifying questions to understand the app's purpose (e.g., personal reminders, social coordination, gift suggestions) and target users. Define what success looks like.

2. Segment Users and Identify Needs

Break down potential users (e.g., busy professionals, social butterflies, family organizers) and map their core jobs-to-be-done and pain points around birthdays.

3. Brainstorm and Prioritize Features

Generate a broad set of features (e.g., reminders, gift ideas, group cards, event planning) and prioritize using a framework like RICE or impact/effort matrix.

4. Define MVP and Roadmap

Select a minimal set of features for the first release that delivers core value, then outline subsequent phases with clear milestones.

5. Define Success Metrics and Iterate

Identify key metrics (e.g., DAU, reminder engagement, gift purchase conversion) and plan for user feedback loops to guide future iterations.

Key Points to Mention

  • User segmentation and jobs-to-be-done to ground feature decisions in real needs
  • Prioritization frameworks (e.g., RICE, Kano) to justify feature choices
  • MVP definition and phased roadmap to show execution thinking
  • Success metrics (e.g., engagement, retention, conversion) tied to product goals
  • Potential monetization strategies (e.g., affiliate partnerships, premium features) without compromising user experience
  • Competitive landscape and differentiation (e.g., integration with calendars, social networks)
