Summary

Google PM interview with a single open-ended product design question. Pretty short on details but the question itself has a lot of room to run with.

Questions Asked (1)

Q1

Design an elevator. Think big and be creative.

I went straight to the basics first, capacity, floors, buttons, which in hindsight was probably the most boring possible read of the prompt.

Suggested Approach

Start by clarifying the scope and goals of the elevator design—who are the users, what building type, and what constraints exist—then propose a bold, user-centric vision that leverages emerging technologies. Structure your answer around a clear framework that balances creativity with feasibility, and be ready to iterate based on feedback.

Pro tip: Anchor your creative ideas in a deep understanding of user pain points and business viability; Google values moonshots that are grounded in real user needs and have a plausible path to implementation.

1. Clarify Objectives and Constraints

Ask questions to understand the context: Is this for a skyscraper, a low-rise, or a new city? Who are the primary users? What are the budget, safety, and regulatory constraints? This ensures your design is relevant and addresses real needs.

2. Define User Personas and Pain Points

Identify key user groups (e.g., daily commuters, elderly, disabled, delivery robots) and their frustrations with current elevators: wait times, crowding, accessibility, energy efficiency. This human-centered lens will drive meaningful innovation.

3. Brainstorm Bold Solutions

Generate creative ideas that address the pain points: AI-powered predictive dispatching, personalized destination control, modular elevator pods that move horizontally and vertically, energy-regenerative systems, or integration with building IoT for seamless journeys.

4. Prioritize and Prototype

Evaluate ideas based on impact vs. feasibility. Select one or two high-potential concepts to develop further, outlining a minimal viable product (MVP) and how you would test it (e.g., simulation, pilot in a Google office).

5. Define Success Metrics and Iterate

Propose metrics like average wait time, user satisfaction, energy consumption, and throughput. Describe how you would gather feedback and iterate to improve the design over time.

Key Points to Mention

  • User-centric design: focus on reducing wait times, improving accessibility, and personalizing the experience.
  • Leveraging emerging technologies: AI for predictive analytics, IoT for seamless integration, and robotics for autonomous operation.
  • Sustainability: energy-efficient designs, regenerative braking, and eco-friendly materials.
  • Scalability and adaptability: design that can be applied to different building types and future urban mobility ecosystems.
  • Safety and reliability: redundant systems, emergency protocols, and compliance with standards.
  • Business viability: cost-benefit analysis, potential revenue models (e.g., advertising, premium services), and ROI for building owners.
