In my recent Node.js and backend development interview process, I aimed to showcase my expertise in building robust and scalable server-side applications. The interview began with a technical screening that included coding challenges and questions on fundamental JavaScript and backend concepts. This was followed by a series of technical interviews where I discussed my experience with creating RESTful APIs using Node.js and Express.js, implementing middleware, handling asynchronous operations, and integrating with databases such as MongoDB and SQL.
