Summary

Google product design interview with a single open-ended prompt about self-driving cars. Not a lot of context given upfront, which made it feel pretty wide open in a slightly uncomfortable way.

Suggested Approach

Start by clarifying the scope and constraints of the self-driving car feature, then propose a user-centric feature that addresses a real pain point, and finally outline how you would validate and iterate on it. Focus on demonstrating structured thinking, technical feasibility, and alignment with Google's mission.

Pro tip: Anchor your feature in a specific user scenario and quantify its potential impact (e.g., safety, efficiency, or accessibility) to show you think like a product engineer, not just a coder.

1. Clarify the problem space

Ask questions to understand the target user, use case, and constraints (e.g., level of autonomy, regulatory environment, existing features). This shows you avoid assumptions and scope the problem effectively.

2. Identify a user need or opportunity

Choose a specific pain point or opportunity (e.g., reducing motion sickness, improving accessibility for disabled riders, optimizing energy efficiency) and justify why it matters.

3. Propose the feature

Describe the feature clearly, including how it works from a user and technical perspective. Explain how it leverages sensors, AI, or data to deliver value.

4. Assess feasibility and impact

Discuss technical challenges, required data, potential risks, and how you would measure success (e.g., safety metrics, user satisfaction, adoption rate).

5. Outline validation and iteration

Explain how you would test the feature (simulations, pilot programs) and iterate based on feedback, emphasizing safety and continuous improvement.

Key Points to Mention

  • Safety as a non-negotiable priority in any self-driving feature
  • Use of sensor fusion and real-time data processing
  • Personalization and adaptability to individual user preferences
  • Scalability and integration with existing autonomous systems
  • Regulatory and ethical considerations (e.g., privacy, liability)
  • Metrics for success: safety, efficiency, user experience, and accessibility
