What this question tests
Whether you can ground a hypothetical roadmap in a realistic read of a discontinued product's actual fate and differentiators.
How to approach it
- Acknowledge the real context directly: Google Inbox was shut down in 2019 as Google consolidated its email experience into Gmail.
- Clarify what's being asked: a design exercise imagining Inbox's product direction, distinct from arguing the business strategy question.
- Identify Inbox's actual product differentiators: smart bundling of related emails, snooze, and a cleaner, action-oriented interface.
- Propose a roadmap prioritizing those differentiators, like smarter auto-categorization and one-tap actions, over rebuilding generic email features.
- Design around the real reason it likely struggled, low adoption relative to Gmail, by proposing tighter integration rather than a fully separate app.
- Define success metrics: reduction in time to inbox zero, and a guardrail on user confusion from running two competing email products.
What a strong answer includes
- Grounds the roadmap in the real, known outcome that Inbox was discontinued, rather than pretending it's still a thriving product.
- Identifies concrete Inbox differentiators, bundling and snooze, instead of a generic list of email features.
- Reasons about why adoption likely lagged Gmail, and designs the roadmap to address that root cause.
- Proposes integrating Inbox's ideas into Gmail rather than running two products, matching what actually happened.
Common mistakes
- Designing a roadmap as though Inbox were a healthy, growing standalone product with no acknowledgment of reality.
- Listing generic email features without identifying what specifically made Inbox different from Gmail.
Likely follow-up questions
- Why do you think Inbox ultimately failed to displace Gmail?
- Which Inbox-only feature do you think Gmail should still adopt today?
