Mock interview — REST API design (Node.js + Express)

A mock interview focused on REST API design with Node.js and Express. It evaluates how you model resources, how you validate input, how you handle errors in a centralized way and which basic security measures you apply. Suggested duration: 45 minutes. Answer on your own first, before reading the suggested answer.

Note: the goal is not for you to memorize every status code, but for you to reason through the design and explain why you make each decision.
