Node.js Machine Coding Round Questions

Preparing for a machine coding interview can be a daunting task, especially for developers focusing on Node.js. These interviews often assess problem-solving skills and coding proficiency in real-time, testing your ability to write efficient and scalable code. Here are some common types of questions you might encounter.

1. Build a RESTful API

One common question involves creating a basic RESTful API. Candidates might be asked to design endpoints for CRUD operations on a resource, such as a user or a product. This section tests your understanding of routing, middleware, and database integration, often requiring the use of an ORM like Sequelize or Mongoose.

2. Implement Real-time Features

Another popular scenario is implementing real-time functionalities using WebSockets. You may be asked to create a simple chat application that allows users to communicate instantaneously, testing your knowledge of event-driven architectures.

3. Error Handling

Interviews may also include questions on error handling strategies in Node.js. You should be prepared to discuss synchronous vs. asynchronous error handling and demonstrate how to implement custom error classes or middleware.

In summary, practicing these scenarios will help you enhance your problem-solving skills while showcasing your versatility as a Node.js developer. Good luck!
