Web Development Interview Questions for Freshers
1. What happens when you type a URL in your browser and press Enter?
Answer:
DNS lookup happens to find the IP address
Browser sends an HTTP/HTTPS request to the server
Server processes and sends back HTML/CSS/JS
Browser renders the page using its rendering engine
2. What is the difference between GET and POST requests?
Answer:
GET: Sends data in the URL, used for fetching data
POST: Sends data in the body, used for submitting data securely
3. What is a responsive website?
Answer:
A responsive website adjusts layout and design based on screen size and device (mobile, tablet, desktop), usually using CSS media queries.
4. What is the role of Webpack in web development?
Answer:
Webpack bundles JavaScript files, CSS, and assets into optimized output for faster website loading and better performance.
5. What is the purpose of async and defer in script tags?
Answer:
async: Loads script asynchronously and executes it immediately
defer: Loads script asynchronously but executes after HTML is parsed
6. What is the difference between localStorage and sessionStorage?
Answer:
localStorage: Stores data with no expiration
sessionStorage: Stores data until the browser tab is closed
7. What is CORS?
Answer:
CORS (Cross-Origin Resource Sharing) is a browser security feature that restricts cross-domain API calls unless the server allows it.
8. What is the difference between null and undefined in JavaScript?
Answer:
undefined: A variable declared but not assigned a value
null: A variable explicitly set to have no value
9. How do you optimize website performance?
Answer:
Minify CSS/JS

Use a CDN
10. What is the DOM?
Answer:
DOM (Document Object Model) represents the structure of an HTML document as objects, which JavaScript can interact with to change content dynamically.

Web Development Interview Questions Part-2
11. What are semantic HTML elements?
Answer:
Semantic elements clearly describe their meaning in a human- and machine-readable way. Examples: <header>, <footer>, <article>, <nav>.
12. What are HTTP status codes?
Answer:
They indicate the result of an HTTP request.
Common ones:
200 OK (Success)
404 Not Found
500 Internal Server Error
401 Unauthorized
403 Forbidden
13. What is the box model in CSS?
Answer:
The box model includes:
Content
Padding
Border
Margin
It defines how space is taken up around HTML elements.
14. What are pseudo-classes in CSS?
Answer:
Pseudo-classes style elements based on their state.
Examples:
:hover (when mouse is over)
:first-child
:nth-child()
15. How do you make a website SEO-friendly?
Answer:
Use semantic HTML
Add meta tags and alt text
Mobile responsiveness
Fast loading speed
Proper URL structure
16. What is the difference between synchronous and asynchronous in JavaScript?
Answer:
Synchronous: Code runs line by line
Asynchronous: Tasks like API calls don't block other code; use callbacks, promises, or async/await
17. What is a promise in JavaScript?
Answer:
A Promise represents the result of an async operation.
It can be:
Pending
Fulfilled
Rejected
18. What is event bubbling and capturing in JavaScript?
Answer:
Bubbling: Event propagates from child to parent
Capturing: Event goes from parent to child
You can control it using event.stopPropagation()
19. What is a CDN?
Answer:
CDN (Content Delivery Network) delivers static files (images, CSS, JS) via servers closest to the user to improve website speed.
20. What tools do you use for version control?
Answer:
Most common: Git + GitHub
Git tracks changes in code, and GitHub helps you collaborate and manage versions.

Interviewer: You have 2 minutes. Explain the JavaScript Event Loop to me.
My answer: Challenge accepted, letโs go!
โค Single-Threaded Execution:
JavaScript is single-threaded, which means it can only execute one task at a time. This is managed by the call stack, where functions are executed one by one.
โค Call Stack: Think of the call stack as a stack of plates. Every time a function is called, a new plate (function) is added to the stack. When the function finishes, the plate is removed from the stack.
โค Web APIs: For asynchronous operations like
โค Callback Queue: When an asynchronous operation completes, its callback is placed in the callback queue. This queue waits until the call stack is clear before pushing the next callback onto the stack.
โค Event Loop: The event loop is like a manager that constantly checks if the call stack is empty. When it is, the event loop takes the first callback from the callback queue and adds it to the call stack.
โค Microtasks Queue: There's also a microtasks queue for tasks like promises. This queue has higher priority than the callback queue. The event loop checks the microtasks queue first, ensuring these tasks are processed before other callbacks.
โค Priority Handling: To sum it up, the event loop first checks the microtasks queue. If it's empty, it moves to the callback queue. This ensures that critical tasks, like promises, are handled promptly.
Thatโs the JavaScript Event Loop.

Starting with coding is a fantastic foundation for a tech career. As you grow your skills, you might explore various areas depending on your interests and goals:
โข Web Development: If you enjoy building websites and web applications, diving into web development could be your next step. You can specialize in front-end (HTML, CSS, JavaScript) or back-end (Python, Java, Node.js) development, or become a full-stack developer.
โข Mobile App Development: If you're excited about creating apps for smartphones and tablets, you might explore mobile development. Learn Swift for iOS or Kotlin for Android, or use cross-platform tools like Flutter or React Native.
โข Data Science and Analysis: If analyzing and interpreting data intrigues you, focusing on data science or data analysis could be your path. You'll use languages like Python or R and tools like Pandas, NumPy, and SQL.
โข Game Development: If youโre passionate about creating games, you might explore game development. Languages like C# with Unity or C++ with Unreal Engine are popular choices in this field.
โข Cybersecurity: If you're interested in protecting systems from threats, diving into cybersecurity could be a great fit. Learn about ethical hacking, penetration testing, and security protocols.
โข Software Engineering: If you enjoy designing and building complex software systems, focusing on software engineering might be your calling. This involves writing code, but also planning, testing, and maintaining software.
โข Automation and Scripting: If you're interested in making repetitive tasks easier, scripting and automation could be a good path. Python, Bash, and PowerShell are popular for writing scripts to automate tasks.
โข Artificial Intelligence and Machine Learning: If you're fascinated by creating systems that learn and adapt, exploring AI and machine learning could be your next step. Youโll work with algorithms, data, and models to create intelligent systems.
Regardless of the path you choose, the key is to keep coding, learning, and challenging yourself with new projects. Each step forward will deepen your understanding and open new opportunities in the tech world.
