Summary

Google PM interview with a single market sizing and segmentation question built around a hypothetical smell-detection technology. Pretty open-ended, which I wasn't fully prepared for.

Questions Asked (1)

Q1

A third-party company has the ability to detect smells. How would you size the market opportunity, and which customer segment would you prioritize?

I spent way too long on the market sizing part and kind of rushed the segmentation.

Suggested Approach

Start by clarifying the technology's capabilities and constraints, then size the market using a top-down and bottom-up approach, and finally prioritize a customer segment based on pain point severity, willingness to pay, and strategic fit. Structure your answer to show both analytical rigor and product intuition.

Pro tip: Anchor your market sizing in a specific use case (e.g., quality control in food manufacturing) rather than trying to size the entire 'smell detection' market, which is too broad. This demonstrates focus and practical product thinking.

1. Clarify the Technology

Ask questions to understand the technology's capabilities: What smells can it detect? What is the sensitivity, accuracy, and cost? Is it a hardware device, software, or a service? This defines the solution space.

2. Identify Potential Use Cases

Brainstorm applications across industries such as healthcare (disease detection), food and beverage (quality control), environmental monitoring, safety (gas leaks), and consumer products (fragrance).

3. Size the Market

For the most promising use cases, estimate the total addressable market (TAM) using top-down (industry reports) and bottom-up (number of potential customers × price) methods. Consider adjacent markets and expansion potential.

4. Prioritize Customer Segments

Evaluate segments based on criteria like pain point severity, willingness to pay, adoption barriers, competition, and strategic fit with Google's strengths (e.g., AI, cloud). Use a scoring matrix to compare.

5. Recommend a Segment and Go-to-Market Strategy

Choose one segment to prioritize, justify your choice, and outline a high-level GTM plan including value proposition, channels, and potential partnerships.

Key Points to Mention

  • Clarify the technology's capabilities and limitations before sizing the market.
  • Use both top-down and bottom-up market sizing methods for credibility.
  • Consider multiple industries but focus on one or two for deep analysis.
  • Prioritize segments based on pain point severity, willingness to pay, and strategic fit.
  • Leverage Google's strengths such as AI, machine learning, and cloud infrastructure.
  • Discuss potential go-to-market strategies and partnerships for the chosen segment.
