This is basically a full PM loop compressed into one question.
Choose a product you know deeply and can critique constructively, then structure your answer around a clear user-centric narrative: define the user and goal, propose a feature that addresses a real pain point, and walk through prioritization, metrics, and execution with cross-functional collaboration. Show Google-scale thinking by considering trade-offs, data-driven decisions, and how you'd align stakeholders.
Pro tip: Pick a product that is widely used but has a clear gap you can articulate—this shows product sense and avoids niche choices that may confuse the interviewer. Quantify the opportunity with rough estimates (e.g., TAM, impact) to demonstrate business acumen.
Briefly describe the product, its primary user segments, and its core goal. Explain how you know this (e.g., from usage patterns or public data).
State the north-star metric for the product, then propose a new feature that addresses an unmet user need. Clearly articulate the user problem and why it's worth solving.
Explain how you'd prioritize this feature against other opportunities (e.g., RICE, impact/effort) and outline a high-level build approach, including any technical or design considerations.
Specify success metrics (e.g., adoption, engagement, retention) and describe experiments (A/B tests, user studies) to validate the feature and measure impact.
Describe how you'd align engineering, design, marketing, and leadership by communicating the vision, sharing data, and addressing concerns to secure resources and support.
