What this question tests

Ownership and prioritization for an existing product: can the candidate diagnose the current state and pick a focused next move.

Clarify the current state of Facebook Shop with the interviewer, since strategy depends on whether it is early stage or mature.
Identify the two sides: shoppers browsing within Facebook and Instagram, and merchants, often small businesses, managing storefronts.
Name the likely core problem: social commerce has lower purchase intent than a dedicated marketplace, so conversion from browse to purchase is likely the bottleneck.
Propose a focus area: reduce checkout friction (native checkout instead of redirecting to the merchant's own site) and improve product discovery through creator and influencer tagging.
Prioritize checkout friction first since it is the most direct lever on conversion, a likely binding constraint.
Define success as browse to purchase conversion rate and merchant retention (active sellers month over month).

Diagnoses the likely core constraint, low purchase intent in a social context, rather than jumping straight to random feature ideas.
Picks checkout friction as the highest leverage fix, since native checkout has repeatedly proven to lift conversion in social commerce.
Names both sides of the marketplace, merchant retention and shopper conversion, instead of optimizing only for one.

Proposing generic e-commerce features without diagnosing what is actually broken in the current funnel.
Focusing only on the shopper side and ignoring merchant retention, which is what keeps supply on the platform.

How would you convince merchants to use native checkout instead of their own site?
What would you measure in the first 90 days to know this is working?
