Summary

PM interview at Google that basically asked me to be a consultant for 45 minutes. One big meaty question about Model-Based Engineering, pitched to a hypothetical exec audience. Felt more like a strategy presentation than a product interview.

Questions Asked (1)

Q1

Walk a non-technical Google executive through Model-Based Engineering: what it is, why it matters for hardware development, the benefits and trade-offs compared to traditional approaches, and a phased rollout plan covering tooling, process changes, and success metrics.

Suggested Approach

Start with a simple analogy to explain MBE, then connect it to Google's hardware goals and product strategy. Structure your answer around benefits, trade-offs, and a phased rollout with clear metrics, emphasizing cross-functional alignment and executive-level impact.

Pro tip: Acknowledge that MBE is a cultural shift, not just a tool change; highlight the need for executive sponsorship and early wins to drive adoption.

1. Define MBE Simply

Use an analogy like a 'digital twin' or 'virtual prototype' to explain MBE as a way to model, simulate, and optimize hardware before building physical prototypes.

2. Connect to Business Value

Explain why MBE matters for Google's hardware: faster iteration, lower costs, better quality, and enabling complex designs like AR/VR or data center hardware.

3. Compare Benefits and Trade-offs

Contrast MBE with traditional approaches: benefits include reduced physical testing and faster time-to-market; trade-offs include upfront investment, tool complexity, and cultural resistance.

4. Outline Phased Rollout

Propose a phased plan: pilot with a small team, then scale; cover tooling (e.g., simulation software), process changes (e.g., cross-functional collaboration), and success metrics (e.g., time saved, cost reduction).

5. Emphasize Cross-functional Alignment

Highlight how MBE requires collaboration between engineering, product, and leadership; suggest regular check-ins and training to ensure adoption.

Key Points to Mention

  • Digital twin concept for hardware
  • Reduced physical prototyping costs and time
  • Improved design accuracy and innovation
  • Upfront investment in tools and training
  • Cultural shift and change management
  • Metrics like time-to-market, cost per iteration, and defect rates
