Real Interview Questions Asked – Freshers Role
Q1. Explain the MERN stack and why each technology is used.
Candidate Answer:
“MERN stands for MongoDB, Express.js, React.js, and Node.js. MongoDB stores JSON-like documents. Express handles backend routes and middleware. React manages the frontend UI. Node allows server-side JS execution. Together, they form a seamless JS stack.”
Feedback: Strong base. Good articulation.
Q2. Can you build a REST API in Node.js? Walk through the steps.
Candidate Answer:
“Install Express, create routes using app.get, app.post, connect to MongoDB using Mongoose, and test using Postman.”
Feedback: Clear understanding. Could elaborate more on middleware and error handling.
Q3. What’s the difference between SQL and NoSQL?
Candidate Answer:
“SQL is relational and uses structured schema, while NoSQL like MongoDB is document-based and more flexible.”
Feedback: Crisp and correct.
Q4. How do you handle async operations in React?
Candidate Answer:
“Using useEffect() hook and async/await inside it or with external functions.”
Feedback: Good awareness.
Q5. Can you explain the concept of virtual DOM?
Candidate Answer:
“It’s a lightweight copy of the real DOM. React updates it first and compares changes before applying to the actual DOM.”
Feedback: Excellent clarity.
