How interviewers test REST APIs
Real questions from Skilture's interview banks, with what the interviewer is listening for.
AI Engineer · intermediate
You need to expose an AI model's inference capabilities as a service. Describe the key components of a REST API you would design for this purpose, including endpoints, request/response formats, and error handling.
Listen for: The candidate should detail standard HTTP methods, clear endpoint naming, JSON request/response bodies, and appropriate HTTP status codes for error reporting. A red flag would be a lack of understanding of REST principles or basic API design.
Backend Developer · intermediate
What are the key principles of RESTful API design? Give an example of a well-designed REST endpoint.
Listen for: A strong answer will cover statelessness, client-server architecture, uniform interface (resources, representations, HATEOAS), and provide a clear, resource-based URL example. A red flag is confusing REST with SOAP or not understanding resource orientation.
Full Stack Developer · intermediate
Walk me through what happens end-to-end when a user submits a form on a full-stack app you built.
Listen for: Strong answers trace the request from client validation, through the HTTP call, server validation, database write, and response back to the UI state. Skipping validation or error handling on either side is a red flag.
