Can you discuss the main elements of a web API?
You know the technical question. When interviewing for a back end developer's role, most of the questions you will be asked will be technical. These questions allow the interviewer to confirm your skills and experience while determining if these match the requirements of the role they are interviewing for. The best way to prepare for an interview is to study the processes you use daily and the technical terminology associated with them. This will keep the information fresh in your mind. You should also practice answering questions like these.
"There are several critical elements when defining a web API. These include statements communication, XML and JSON formatting languages, HPPT for communication between the client and the server, and simple URI for services."
Community answers are written by other candidates practicing this set. Reading how others frame the same question is one of the fastest ways to sharpen your own.

A web API handles requests and sends responses using HTTP protocol across the internet. A web API has a load balancer to allocate requests to servers running the application to prevent server overload. It has a router to direct each request to the appropriate resource on the server to handle it. It has views that handle requests, make queries to a database, and return responses typically formatted as JSON or XML.
