What this question tests
Product design for a two-context rating system, checking whether you can recognize that dining and delivery ratings measure fundamentally different things.
How to approach it
- Clarify the distinction: a dine-in rating reflects ambiance and service, while a delivery rating reflects food packaging, temperature, and delivery timeliness, so one rating conflates two different experiences.
- Identify the core pain point: current single ratings mislead users, a restaurant with great dine-in service might have poor delivery packaging, or vice versa.
- Prioritize splitting the rating into two distinct scores over adding more granular sub-categories, since a simple split solves the biggest confusion first.
- Propose a design: separate dine-in and delivery rating scores shown contextually, dine-in when browsing for reservations, delivery when browsing for orders.
- Address data collection: prompt delivery-specific feedback right after order completion, focused on packaging and temperature, separate from a general star rating.
- Define success as improved rating prediction accuracy, measured by correlation between shown ratings and actual post-experience satisfaction for each context.
What a strong answer includes
- Names the core insight precisely, dine-in and delivery measure different things, rather than proposing generic rating improvements.
- Proposes contextual display of the split rating, showing the right rating in the right browsing context rather than showing both everywhere and confusing users.
- Ties success to a measurable accuracy improvement, not just having more data points.
Common mistakes
- Proposing to average the two experiences into one score, which perpetuates the exact confusion the question is asking you to fix.
- Adding too many rating sub-categories at once, overwhelming users instead of solving the core dine-in versus delivery confusion.
Likely follow-up questions
- How would you handle restaurants that only offer one of the two services?
- How would you prevent rating fatigue from asking for feedback after every order?
