API design interviews test your ability to create intuitive, scalable, and well-documented APIs. Practice the questions about REST conventions, versioning, and developer experience.
Sample questions
These are the kinds of questions you'll drill. Real mock rounds will generate many more — tailored to the exact JD you paste in.
How do you design a RESTful API for a resource with complex relationships?
When would you choose GraphQL over REST? What are the trade-offs?
Walk me through your approach to API versioning and backward compatibility.
How do you handle pagination, filtering, and sorting in a REST API?
Describe your approach to API authentication and rate limiting.
Reading API Design questions isn't the same as answering them live. You need the rep — the pause, the clarifying question, the moment where you realize you forgot the framework. We put you in that exact spot, then show you what a strong answer would have looked like.
