Product design question

Midjourney often starts with product ideas that have no clear precedent. Pick a new creative workflow concept and walk me through how you would take it from vague idea to a launchable MVP: how you would identify the user problem, choose the riskiest assumptions to test first, and decide what belongs in v1 versus what you would explicitly defer.

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

Tests taking a precedent-free creative workflow idea from concept to a launchable MVP by identifying the user problem and sequencing risk-testing.

Pick a specific concept, for example a collaborative multi-user prompting session, rather than speaking about MVP process abstractly.
Identify the underlying user problem precisely, for example creators wanting real-time feedback from collaborators mid-generation rather than sharing static outputs after the fact.
List the riskiest assumptions: whether users actually want real-time collaboration on a solo creative tool, and whether the interaction model is usable at all.
Design the smallest test for the riskiest assumption first, a rough prototype letting two users influence one generation, before building full real-time infrastructure.
Scope v1 narrowly around validating that assumption, deferring polish, scale, and secondary features like permissions or history to later versions.
Define what belongs in v1 versus deferred explicitly, for example basic two-person sessions in v1, larger group sessions and saved collaboration history deferred.

Tests the riskiest assumption, real demand for real-time collaboration, before investing in full infrastructure.
Names a concrete v1 scope, two-person sessions only, and explicitly defers scale and secondary features.
Grounds the whole exercise in one specific concept rather than describing MVP methodology in the abstract.

How would you measure whether the riskiest assumption was validated?
What would you do if the prototype showed users wanted the feature but not the interaction model you built?
