I kind of assumed they wanted me to describe what already exists and then improve on it, but I think that was the wrong instinct.

Suggested Approach

Start by clarifying the user problem and constraints, then propose a version control system that balances simplicity with power, and finally discuss trade-offs and success metrics. Emphasize how your solution integrates with Google's ecosystem and leverages existing strengths.

Pro tip: Show awareness of Google's existing products like Drive's version history and suggest enhancements rather than reinventing the wheel. Highlight how you'd validate the feature with user research and A/B testing to ensure it meets real needs without overwhelming casual users.

1. Clarify the Problem and User Needs

Ask clarifying questions to understand the target users, use cases, and pain points with current version control in Google Docs. Identify what 'version control' means in this context—simple history, branching, merging, or collaborative editing?

2. Define Goals and Success Metrics

Outline the objectives: improve collaboration, reduce errors, increase user satisfaction, etc. Define measurable success metrics such as adoption rate, reduction in version conflicts, or time saved.

3. Propose a Solution with Key Features

Describe a version control system that includes features like named versions, branching, merging, diff view, and rollback. Consider how to make it intuitive for non-technical users while powerful for advanced users.

4. Address Technical and Design Trade-offs

Discuss trade-offs such as complexity vs. simplicity, performance impact, storage costs, and integration with existing Google infrastructure. Explain how you'd prioritize features based on user impact and effort.

5. Plan for Validation and Iteration

Outline a rollout plan: prototype, user testing, A/B testing, and gathering feedback. Explain how you'd iterate based on metrics and user feedback to refine the feature.

Key Points to Mention

Leverage existing Google Drive version history and enhance it with branching/merging capabilities.
Consider real-time collaboration implications: how version control interacts with simultaneous editing.
Prioritize user experience: make advanced features discoverable but not overwhelming for casual users.
Define clear success metrics (e.g., adoption, reduction in version-related errors, user satisfaction).
Address technical challenges: storage, performance, conflict resolution algorithms.
Discuss competitive landscape: how Google Docs version control would compare to Microsoft Word or other tools.
