Summary

Google PM interview, one question about what you'd build with a billion dollars and generative AI. Pretty open-ended, which sounds fun until you're actually sitting there trying to not sound like every other candidate who says 'an AI assistant for X.'

If you had $1 billion to spend, what would you build using generative AI?

Suggested Approach

Start by clarifying the goal: is this a for-profit product, a public good, or a strategic bet for Google? Then pick a specific, high-impact problem where generative AI provides a 10x improvement, and outline a product vision with target users, value proposition, and a path to sustainability. Show structured thinking by segmenting the market, prioritizing opportunities, and explaining how you'd allocate the $1B across build, scale, and monetization.

Pro tip: Anchor your idea in Google's existing strengths (data, distribution, AI research) and show how it creates a flywheel—e.g., more users → more data → better models → better product. Also, briefly acknowledge risks (safety, regulation, cost) and how you'd mitigate them; this demonstrates product maturity.

1. Clarify the objective and constraints

Ask whether the $1B is for a standalone business, a Google product, or a societal benefit. Clarify success metrics (revenue, users, impact) and time horizon.

2. Identify a high-value problem

Choose a domain where generative AI can create transformative value, such as education, healthcare, or creative tools. Justify why it's worth $1B and why now.

3. Define the product vision

Describe the product: target users, core use cases, and how generative AI is central (not just a feature). Explain the unique value proposition and why existing solutions fall short.

4. Outline a go-to-market and monetization strategy

Explain how you'd acquire users, scale, and generate revenue (e.g., freemium, enterprise, ads). Show how $1B would be allocated across R&D, infrastructure, and marketing.

5. Address risks and measure success

Discuss potential challenges (model bias, cost, competition) and mitigation. Define key metrics (e.g., user retention, cost per query, revenue) to track progress.

Key Points to Mention

Leverage Google's AI research (e.g., Gemini) and distribution channels (Search, Workspace, Android) for competitive advantage.
Focus on a specific user segment and pain point to avoid boiling the ocean.
Show a clear path to monetization, whether through subscriptions, enterprise licensing, or advertising.
Consider the cost of inference and how to optimize model efficiency at scale.
Address ethical and safety concerns, such as misinformation or bias, with concrete guardrails.
Demonstrate iterative product development: start with an MVP, learn, and scale.
