What this question tests

Product sense for a two sided marketplace, focusing on the seller side rather than the more commonly asked buyer side.

Segment merchants: large brands with dedicated teams versus small third party sellers managing everything themselves.
Pick the underserved segment, small sellers, since they have the least tooling and highest churn risk.
Identify their top pain point: inventory and fulfillment visibility, especially demand forecasting for FBA stock levels.
Propose an AI assisted restock recommendation tool that flags stockout risk and overstock before it happens.
Define success: reduction in stockout days for sellers using the tool, adoption rate among small sellers.

Picks a specific, underserved seller segment instead of a generic improve the seller dashboard answer.
Names a concrete, high cost pain point, stockouts and overstock under FBA fees, rather than a cosmetic UI fix.
Gives a believable metric, cutting average stockout days per SKU from an assumed 12 to 6.

Treating merchants as one undifferentiated group instead of segmenting by size and sophistication.
Proposing a UI redesign with no tie to a measurable seller outcome like stockouts or fees.

How would you prioritize this against other seller pain points like return fraud or fee complexity?
How would you validate the forecasting model's accuracy before rollout?
