PureCode Software Full Stack Developer interview questions

In my recent interview for a position requiring expertise in HTML, CSS, MongoDB, and JavaScript, I was first asked to explain the core concepts of HTML and CSS, including semantic HTML and responsive design principles. The interview then focused on my experience with MongoDB, where I was required to discuss schema design, indexing, and aggregation. Specific questions included: "How do you set up a connection between a front-end application and MongoDB using Mongoose?", "What are the advantages of using NoSQL databases like MongoDB over SQL databases?", and "Can you explain the basics of CRUD operations in MongoDB?" Additionally, I was given a practical coding task to create a simple RESTful API using Express.js, integrating MongoDB for data storage. The task required me to demonstrate my understanding of CRUD operations, schema definitions, and query optimizations. The interview concluded with a discussion on best practices in JavaScript, including ES6+ features, asynchronous programming using Promises and async/await, and handling errors effectively in a JavaScript application.
