Photo app for blind users: product design from taking a photo to sharing it
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
As a product manager, you are asked to design a photo app made for people who are blind. Decide whom you would build it for and which of their problems with photos you would solve first, describe what the product would do, and explain how you would know it is working.
```hint Follow one photo
Trace a single photo from the moment it is taken to the moment a friend sees it, and note each step where someone without sight has to ask another person for help.
```
### Clarifying Questions
- Does "blind" mean only people with no usable sight, or also people with low vision who can make out shapes and colors under magnification?
- Should this be a new standalone app or an accessibility mode inside an existing photo product such as Google Photos?
- Is the main use keeping and sharing memories with family and friends, or practical tasks such as reading a letter or checking a label with the camera?
- Is success measured by adoption and engagement among blind users, or is there a revenue goal?
### What a Strong Answer Covers
- Segmentation across the range of vision loss, plus the sighted contacts who send and receive photos, with a reasoned choice of whom to design for first.
- Pain points mapped across the photo journey (taking, reviewing, finding, sharing) and a clear pick of the most central one.
- Audio- and touch-first solutions, including what the product does when an automatic description is wrong or missing.
- Prioritization that weighs impact, effort and dependencies into an MVP and later phases.
- Success metrics that show whether blind users can act on photos independently, with guardrails for accuracy and privacy.
### Follow-up Questions
- The automatic description misidentifies a family member in a photo the user is about to share. How should the product respond, and how would you reduce repeats?
- How would you involve blind users in research and beta testing, and what would you want to learn from them before building?
- If descriptions were built into the phone's screen reader and played by default, how would you tell real usefulness apart from forced usage?
Overview: A product design question asking a PM to create a photo app for people who are blind. It tests segmenting users across levels of vision loss, mapping pain points in taking, finding and sharing photos, designing audio-first solutions, prioritizing an MVP and choosing success metrics.
