Summary

Meta product design interview, one question about building a spreadsheet experience for mobile. Pretty open-ended and I spent the first few minutes just trying to figure out what angle they actually wanted.

I went straight to the UI constraints and probably should've started with the user first.

Suggested Approach

Start by clarifying the goal and target users, then outline the core user needs and pain points for mobile spreadsheet use. Propose a high-level design that prioritizes mobile-first interactions, and discuss key trade-offs and success metrics.

Pro tip: Emphasize that mobile spreadsheets are not just smaller versions of desktop; they require rethinking input methods and collaboration. Show awareness of Meta's ecosystem by suggesting integration with Messenger or WhatsApp for sharing and commenting.

1. Clarify Goals and Users

Ask clarifying questions to understand the purpose (e.g., personal vs. enterprise), target users (e.g., casual vs. power users), and key constraints (e.g., offline access, device types).

2. Identify User Needs and Pain Points

Brainstorm the main jobs-to-be-done for mobile spreadsheet users, such as quick data entry, viewing, simple edits, and collaboration. Highlight pain points like small screen, touch input, and limited processing power.

3. Propose High-Level Design

Outline the core features and user flows, focusing on mobile-first interactions (e.g., voice input, gesture-based navigation, simplified formulas). Consider platform-specific capabilities like camera for data capture.

4. Discuss Trade-offs and Technical Considerations

Address key trade-offs such as feature richness vs. simplicity, offline vs. online, and performance vs. battery life. Mention technical choices like using a cross-platform framework or native development.

5. Define Success Metrics and Iterate

Propose metrics to measure success (e.g., daily active users, task completion time, retention) and suggest an iterative approach based on user feedback.

Key Points to Mention

  • Mobile-first design: prioritize touch, voice, and camera input over keyboard/mouse.
  • Simplified feature set: focus on viewing, quick edits, and comments rather than complex formulas.
  • Collaboration and sharing: integrate with messaging apps for easy sharing and real-time co-editing.
  • Offline capability: allow basic viewing and editing without internet, with sync when online.
  • Performance and battery: optimize for low latency and efficient resource usage.
  • Security and privacy: ensure data protection, especially for enterprise users.
