When it comes to designing RESTful APIs, it is crucial to have a clear understanding of the principles and best practices. As RESTful APIs are widely used in web development, it is common for employers to ask specific questions during interviews to assess a candidate’s knowledge and expertise in this area. In this article, we will explore some common REST API design interview questions that you may encounter during your job search.
Before diving into the questions, it is important to note that REST (Representational State Transfer) is an architectural style used for designing networked applications. It is based on a set of principles, such as the use of HTTP methods (GET, POST, PUT, DELETE) for data manipulation and the use of URIs (Uniform Resource Identifiers) to identify resources. A well-designed RESTful API should be scalable, stateless, and easy to understand.
Now, let’s take a look at some common interview questions related to REST API design:
See these REST API design interview questions:
