How would you propose an MVP for a social sharing feature?

WHAT THIS TESTS: This question evaluates whether you can translate a broad product request into a bounded, testable technical proposal. The interviewer cares about scope decomposition, risk reduction, and your ability to distinguish user-facing value from engineering polish. They want to see that you treat MVP as a learning tool, not just a smaller backlog.

A GOOD ANSWER COVERS: Four things in order. First, requirement triage: ask which of the 10 requirements map to the core user journey of creating content, sharing it, and consuming it. Second, a one-sprint technical slice: propose an authenticated share action, a stable API endpoint that generates a shareable reference, and a minimal destination feed that renders shared content without rich previews or reactions. Third, explicit exclusions: state what is deferred, such as analytics dashboards, edit-after-share, or granular privacy controls. Fourth, validation plumbing: include basic event logging and a single success metric, such as share completion rate, so the PM can decide whether to invest in the remaining two sprints.

COMMON WRONG ANSWERS: Two red flags dominate. One is the horizontal slice, where you shave 30 percent off every requirement and deliver a brittle version of all 10 items. That produces no usable feedback because nothing actually works end to end. The other is confusing MVP with a hackathon prototype: dropping tests, omitting auth, or skipping error handling under the guise of speed. A senior interviewer will flag this as irresponsible scoping.

LIKELY FOLLOW-UPS: Expect the interviewer to push on specific trade-offs. They may ask how you would handle a spike in traffic if the share button goes viral, which tests whether your minimal feed can scale or at least degrade gracefully. They may also ask what you would cut if the one-sprint estimate slips to two weeks, forcing you to rank auth versus feed rendering.

ONE CONCRETE EXAMPLE: Suppose the 10 requirements include OAuth, image upload, caption editing, friend tagging, a news feed, push notifications, like counts, deep linking, an admin panel, and a recommendation engine. The MVP is OAuth plus deep linking plus the news feed. A user authenticates, uploads one image with a plain text caption, and sees it in a chronologically sorted feed shared with friends. Everything else waits. This gives the PM real adoption data in one sprint instead of three.
