Behavioral: Present a Product You Helped Create and the Decisions You Made

Tell the interviewer about a product you helped build that you find interesting, and walk them through it. ```hint Lead with the problem Open with the user problem and what made it hard before describing any feature, then make clear which decisions in the story were yours. ``` ### Clarifying Questions - Does it have to be something I built at work, or can it be a side project or a product that never launched? - Should I focus on my own role and decisions, or on the product and how it performed? - Is it fine to pick a product that underperformed, as long as I explain what I learned from it? - How much technical depth do you want compared with the user and business side? ### What a Strong Answer Covers - The user problem and context that made the product worth building, stated briefly. - The candidate's own role, separated from the team's, and the decisions they personally made. - One or two hard trade-offs or prioritization calls, with the alternatives that were considered. - Results measured against the original goal, including what did not work. - What the candidate would do differently and what they took from the experience. ### Follow-up Questions - Which decision would you reverse with what you know now, and what would that have cost at the time? - Where did you disagree with engineering, design or another stakeholder on this product, and how was it resolved? - If you were handed this product today, what would you ship next, and how would you know it worked?
