Summary

Google PM interview with a visual prompt exercise. They showed a picture and asked you to reason through a design decision, which sounds simple but puts you on the spot fast.

Questions Asked (1)

Q1

You're shown a photo of a car with a mirror mounted on the bonnet. Why do you think it was designed that way?

Blanked for a second because I kept trying to think of it as a safety feature and couldn't make that work.

Suggested Approach

Start by clarifying the context and constraints, then hypothesize user needs and design trade-offs. Structure your answer around a user-centered problem-solving framework, and validate assumptions with logical reasoning.

Pro tip: Show adaptability by acknowledging that without more context, multiple valid hypotheses exist, and prioritize them based on likely user scenarios. Demonstrate product sense by linking the design to specific user pain points and business goals.

1. Clarify the Context

Ask questions to understand the car type, target market, and usage scenarios (e.g., is it a vintage car, a specific brand, or a concept vehicle?). This shows you avoid assumptions and gather relevant information.

2. Identify User Needs

Brainstorm potential user needs that a bonnet-mounted mirror could address, such as improved visibility for the driver in certain conditions or for pedestrians. Consider both functional and emotional needs.

3. Analyze Trade-offs

Evaluate the pros and cons of this design compared to standard side mirrors, including cost, aerodynamics, safety regulations, and aesthetics. This demonstrates holistic thinking.

4. Prioritize Hypotheses

Rank the most plausible reasons based on likelihood and impact, and suggest how you would validate them (e.g., user research, competitor analysis). This shows a data-driven approach.

5. Conclude with Product Implications

Summarize how this design decision reflects product strategy, such as targeting a niche market or solving a specific problem, and what it teaches about user-centric design.

Key Points to Mention

  • Improved visibility for the driver, especially in vehicles with limited rear visibility or for specific driving conditions (e.g., towing, off-roading).
  • Safety considerations: mirrors on the bonnet might reduce blind spots or provide a better view for the driver in certain positions.
  • Aesthetic or brand differentiation: some car manufacturers use unique mirror placements as a design signature.
  • Regulatory or market-specific requirements: certain regions may have different mirror placement regulations.
  • Cost and manufacturing trade-offs: bonnet mirrors might be cheaper or easier to install than integrated side mirrors.
  • User experience for pedestrians or other drivers: the mirror might serve to improve awareness of the vehicle's surroundings.
