Designing a refrigerator blind and low-vision users can run without sighted help
Company: Google
Role: Product Manager

Difficulty: medium
Interview Round: Other
Design a refrigerator for people who are blind. Explain which users you would design for, the problems they run into with refrigerators today, what you would build first and why, and how you would know the design works.
```hint Follow the food, not the appliance
Trace a week of food for a blind person: putting groceries away, finding a specific item, judging whether it is still good, noticing the door was left open, and cleaning up. The problems worth solving show up along that path more than in the hardware specification.

### Clarifying Questions
- Is the target user fully blind, or does the brief include low-vision users who rely on magnification and high contrast?
- Does the user live alone, or share the refrigerator with sighted household members who also move things around?
- Are we designing a new appliance to sell, or could part of the answer be an add-on for refrigerators people already own?
- Is there a price target, such as a mainstream mid-range model rather than a premium smart appliance?
### What a Strong Answer Covers
- A specific segment within blind and low-vision users, and the reasoning for focusing on it
- Pain points drawn from the whole food routine (stocking, finding, freshness, safety, controls, cleaning) and ranked by frequency and harm
- Solutions that work through touch and sound without needing a smartphone or internet connection, prioritized into a first release
- Success metrics, and testing with blind users throughout the design
- Trade-offs around cost, reliability, privacy if cameras are involved, and appeal to sighted buyers
### Follow-up Questions
- How would the design change for a household where sighted family members use the same refrigerator?
- If the price target allowed only one new feature, which would you keep and why?
- How would you test the design with blind users before building working hardware?
Overview: A product design question asking how to design a refrigerator for people who are blind or have low vision. It tests user empathy and segmentation, finding pain points across the routine of storing and finding food, prioritizing non-visual solutions, and defining how to measure whether the design works.
