You should be able to explain the fundamentals behind what you build. You should have a basic understanding of questions such as: * What happens when a request reaches a Node.js server? * How does Express middleware work? * How does a React application communicate with an API? * What happens between a frontend button click and a database update? * What is the difference between authentication and authorization? * Why do we use controllers, services, and modules in a backend? * How does asynchronous code work in Node.js? * What happens when an API returns an error? * How would you structure a small backend application? * How do databases and indexes affect API performance? You don't need to know everything. **Strong fundamentals, curiosity, and the ability to understand an existing codebase are more important than knowing a long list of technologies.** If you enjoy understanding how systems work, building features, debugging problems, and learning through real-world development, this internship will give you the opportunity to work with a development team and build practical software engineering skills. **Note:** This is a paid internship.Skills: databases,authentication,node.js,rest,react,api
