This is the kind of question where you either run with it or freeze up trying to figure out what they actually want.
Treat 'time machine' as a metaphor for a product that solves a real user need around time—such as revisiting the past or previewing the future—and frame it as a Google-scale product. Start by clarifying the goal and constraints, then define the user problem, propose a solution, and prioritize features based on impact and feasibility.
Pro tip: Don't get lost in sci-fi; anchor the discussion in a concrete user problem and Google's mission to organize information, showing you can turn an absurd prompt into a strategic product conversation.
Ask questions to understand what 'time machine' means in this context—is it for entertainment, productivity, or information access? Establish constraints like target users, platform, and Google's strategic fit.
Identify a specific, high-value problem such as 'I want to relive memories' or 'I need to predict trends.' Frame it as a user need that Google could address with its data and AI capabilities.
Describe a product concept (e.g., a VR/AR experience, an AI-powered simulation, or a data-driven forecasting tool) and articulate how it solves the user problem better than alternatives.
Outline key features and prioritize them using a framework like RICE or MoSCoW. Define a minimum viable product that delivers core value and can be tested quickly.
Propose metrics (e.g., user engagement, retention, accuracy) and discuss potential risks (ethical, technical, adoption) and mitigation strategies.
