Summary

Google PM interview with a single product design question that sounds deceptively simple but has a lot of moving parts once you actually dig in. The 80% market capture constraint made it feel more like a strategy case than a pure ideation exercise.

Questions Asked (1)

Design a new communication device for elderly users that could capture 80% of the market, with smartphones explicitly off the table.

I spent the first couple minutes just trying to figure out what 'capturing 80%' actually meant as a constraint.

Suggested Approach

Start by clarifying the target market and constraints, then segment elderly users by needs and tech-savviness. Define a product concept that addresses key pain points (usability, accessibility, connectivity) and outline a GTM strategy to capture 80% of the segment, emphasizing distribution and adoption barriers.

Pro tip: Focus on the 'job to be done' for elderly users—often staying connected with family and emergency assistance—rather than just making a simpler phone. Also, consider that capturing 80% market share likely requires a platform play with partnerships (e.g., healthcare providers, senior living communities).

1. Clarify the Market and Constraints

Ask clarifying questions to define the target market size, geography, and what 'elderly' means (age range, tech proficiency). Confirm that smartphones are off the table and that the goal is 80% market share of this new device category.

2. Segment Users and Identify Needs

Divide elderly users into segments based on needs (e.g., health monitoring, social connection, emergency response) and tech comfort. Identify key pain points with existing solutions (smartphones, landlines, basic phones).

3. Ideate Product Solutions

Brainstorm device concepts that address the identified needs, focusing on usability (large buttons, voice control), accessibility (hearing/vision), and connectivity (cellular, Wi-Fi). Consider form factors like wearables, tablets, or dedicated home devices.

4. Define Go-to-Market Strategy

Outline distribution channels (e.g., healthcare providers, senior centers, carriers), pricing models (subscription, subsidized), and partnerships to drive adoption. Address barriers like digital literacy and trust.

5. Validate and Iterate

Propose a validation plan with prototypes and user testing. Discuss metrics for success (adoption rate, engagement) and how to iterate to reach 80% market share.

Key Points to Mention

User-centric design: prioritize simplicity, accessibility (vision, hearing, dexterity), and reliability.
Connectivity and ecosystem: seamless integration with family members' devices, healthcare providers, and emergency services.
Business model: consider hardware + subscription for services like health monitoring or concierge support.
Distribution partnerships: leverage healthcare, senior living, and community organizations to reach the target market.
Adoption barriers: address tech anxiety, privacy concerns, and training/support needs.
Competitive landscape: differentiate from existing solutions like Jitterbug, GrandPad, and Amazon Echo.
