Summary

Google PM interview with a single product design question about fitting a studio apartment for three people. Short session, but the question had more depth to it than I expected going in.

Q1

How would you design a studio apartment intended for three people to live in?

I went straight into space optimization and started rattling off furniture ideas, which was probably the wrong move.

Suggested Approach

Start by clarifying the constraints and user needs: who are the three people, what is their relationship, and what does 'live in' entail? Then, structure your answer around a user-centered design process: define requirements, generate concepts, evaluate trade-offs, and propose a solution with metrics for success.

Pro tip: Frame the problem in terms of user personas and jobs-to-be-done to show empathy, and explicitly discuss trade-offs (e.g., privacy vs. space efficiency) to demonstrate product sense and technical depth.

1. Clarify Constraints and User Needs

Ask questions to understand the context: Are the three people a family, roommates, or something else? What is the budget, location, and duration of stay? What are their daily routines and pain points?

2. Define Requirements and Success Metrics

List functional and non-functional requirements: sleeping arrangements, storage, privacy, communal space, and adaptability. Define success metrics such as satisfaction, space utilization, and cost per person.

3. Generate Design Concepts

Brainstorm multiple layout ideas (e.g., modular furniture, vertical space, shared vs. private zones). Consider innovative solutions like convertible furniture, smart storage, and acoustic partitions.

4. Evaluate Trade-offs and Prioritize

Assess each concept against requirements and constraints. Discuss trade-offs: cost vs. quality, privacy vs. openness, flexibility vs. simplicity. Prioritize features that deliver the most value.

5. Propose a Solution and Iterate

Present a recommended design with a floor plan and key features. Suggest how to test and iterate (e.g., prototypes, user feedback) and how to measure success against metrics.

Key Points to Mention

  • User personas and jobs-to-be-done to ground the design in real needs.
  • Space efficiency techniques: vertical storage, multi-functional furniture, and zoning.
  • Privacy solutions: partitions, scheduling, and personal storage.
  • Trade-offs between cost, comfort, and flexibility.
  • Sustainability and affordability considerations.
  • Metrics for success: user satisfaction, space utilization, and cost per person.
