The Kind of Developer We're Looking For
We are not looking for someone who only knows how to follow tutorials or YouTube projects. 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
