Websockets is a communication protocol providing full-duplex channels over a single TCP connection. It is particularly suited for real-time applications where the server needs to push updates without a client request. This blog post featuring typical Websocket interview questions and answers offers a chance for developers to understand and prepare for discussions around real-time data transmission, and networking protocols during tech interviews. With these questions, one can gauge a candidate’s grasp of handling real-time data and their ability to create effective real-time interactions in web applications.
