Dish Rating System Design | Dataford Interview Questions

Your question is Dish Rating System Design. Take a moment with it on the right.

Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).

Design a system for users to rate dishes from multiple restaurants.

Asked in the Technical interview stage. This is a 30-40 minute discussion with hints, and you may be asked to optimize the design further.

Address the following:

Clarify functional and non-functional requirements.
Define the data model and event pipeline for dishes, restaurants, users, ratings, and reviews.
Design any ML components that personalize dish discovery or predict rating quality.
Explain offline training, online serving, feature freshness, and feedback loops.
Cover evaluation, monitoring, failure modes, and an optimization you would make after the initial design.

Be explicit about assumptions, online versus batch work, cold start, latency, cost, and training-serving skew.
