What this question tests
Product design under an unusual prompt format, testing whether the candidate extracts the real ask, a from-scratch product for a fully blind user, and still grounds it in a real need.
How to approach it
- Interpret the prompt as designing a brand-new product for a completely blind user with no budget constraint, so ambition is explicitly rewarded.
- Pick a specific job to be done, like independent grocery shopping, given the retail companies attached to the question.
- Identify the pain point: blind users can't visually scan shelves, read labels, or compare products and prices independently.
- Propose a concrete solution: an AI-powered wearable that reads labels, compares prices, and narrates aisle navigation, paired with a voice-first checkout flow.
- Define success as percent of shopping trips completed without sighted assistance, and time to complete versus a sighted baseline.
What a strong answer includes
- Grounds 'no constraints, from scratch' in one well-defined job instead of an unfocused feature wish list.
- Explains why blind users can't do this today before jumping to the solution.
- Defines independence, trips completed unaided, as the actual success metric, matching the real user goal.
Common mistakes
- Treating 'no constraints' as license to skip prioritization, producing an unfocused list of features.
- Not connecting the design to the retail context given in the question.
Likely follow-up questions
- If you had to ship a first version in 3 months despite 'no constraints,' what would you cut?
- How would you validate this design with actual blind users before building it?
