Product design question

Design a product to speed up the cooking process?

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 product design ideation and prioritization for a broad, open-ended lifestyle problem, requiring a specific user and pain point to ground it.

Segment the target user: busy working professionals with little time, versus people who enjoy cooking but want efficiency, prioritizing the time-constrained segment since urgency is higher.
Identify the core pain point: meal prep and active cooking time, not the eating itself, is the actual bottleneck for busy people on weeknights.
Propose a hardware-plus-software solution: a smart multi-cooker that accepts a recipe scan or voice command and automatically sets time/temperature, paired with pre-portioned ingredient kits to cut prep time too.
Consider a software-only alternative: a recipe app that optimizes for parallel cooking steps (what to start first, what can wait) to cut total active time without new hardware.
Define success: average total cook time reduction for a standard recipe, and repeat usage frequency, since habit formation on weeknights is the real test of value.

Identifies the real bottleneck, active prep and cook time for busy people, rather than a vague 'make cooking better' framing.
Proposes two distinct solution paths (hardware-assisted and software-only) and reasons about tradeoffs rather than picking one without justification.
Uses an illustrative number, e.g. assume average weeknight meal prep takes 45 minutes and targets cutting that to 20-25 minutes with either solution.
Picks a time-based success metric tied directly to the stated problem, plus repeat usage as a habit-formation signal.

Proposing a solution without first identifying a specific bottleneck (prep time versus cook time versus decision fatigue).
Ignoring that a hardware solution has a much higher cost and adoption barrier than a software-only alternative, without weighing that tradeoff.

Would you build this as hardware or software-only? What would tip that decision?
How would you validate that cook time, not meal decision-making, is really the biggest pain point?
