Product design question

How would you design an app to help people choose which cheese to buy at a grocery store?

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Product sense for a narrow, specific discovery problem, translating a niche need into a focused feature set.

Identify the target user, a shopper overwhelmed by unfamiliar cheese options, unsure what pairs with their meal or fits their taste preference.
Identify the core pain point, cheese aisles have many options with little accessible guidance at the point of decision.
Propose the core feature, scan a cheese's label or barcode to get plain language taste notes, pairing suggestions, and similar alternatives.
Consider a personalization layer, learning from past choices or stated preferences to refine future recommendations.
Define success metrics, percent of scans leading to an add to cart and repeat usage rate on subsequent shopping trips.

Grounds the design in the real decision paralysis moment at the shelf, rather than building a generic recipe or shopping list app.
Proposes a concrete mechanism, barcode scan plus plain language pairing suggestions, that solves the specific in aisle confusion.
Sets a metric tied directly to purchase behavior, scan to cart conversion, rather than just app downloads or opens.

Designing a broad cheese education app instead of a focused in store decision tool.
No mechanism proposed for how the recommendation is generated or personalized.
No metric tied to actual purchase behavior in store.

How would you handle cheeses without existing barcode or database information?
How would you validate that the recommendations are actually good before launch?
