Top Web Development Interview Questions & Answers 🌐💻

📍 1. What is the difference between Frontend and Backend development?
Answer: Frontend deals with the part of the website users interact with (UI/UX), using HTML, CSS, JavaScript frameworks like React or Vue. Backend handles server-side logic, databases, and APIs using languages like Node.js, Python, or PHP.

📍 2. What is REST and why is it important?
Answer: REST (Representational State Transfer) is an architectural style for designing APIs. It uses HTTP methods (GET, POST, PUT, DELETE) to manipulate resources and enables communication between client and server efficiently.

📍 3. Explain the concept of Responsive Design.
Answer: Responsive Design ensures web pages render well on various devices and screen sizes by using flexible grids, images, and CSS media queries.

📍 4. What are CSS Flexbox and Grid?
Answer: Both are CSS layout modules. Flexbox is for one-dimensional layouts (row or column), while Grid manages two-dimensional layouts (rows and columns), simplifying complex page structures.

📍 5. What is the Virtual DOM in React?
Answer: A lightweight copy of the real DOM that React uses to efficiently update only parts of the UI that changed, improving performance.

📍 6. How do you handle authentication in web applications?
Answer: Common methods include sessions with cookies, tokens like JWT, OAuth, or third-party providers (Google, Facebook).

📍 7. What is CORS and how do you handle it?
Answer: Cross-Origin Resource Sharing (CORS) is a security feature blocking requests from different origins. Handled by setting appropriate headers on the server to allow trusted domains.

📍 8. Explain Event Loop and Asynchronous programming in JavaScript.
Answer: Event Loop allows JavaScript to perform non-blocking actions by handling callbacks, promises, and async/await, enabling concurrency even though JS is single-threaded.

📍 9. What is the difference between SQL and NoSQL databases?
Answer: SQL databases are relational, use structured schemas with tables (e.g., MySQL). NoSQL databases are non-relational, schema-flexible, and handle unstructured data (e.g., MongoDB).

📍 🔟 What are WebSockets?
Answer: WebSockets provide full-duplex communication channels over a single TCP connection, enabling real-time data flow between client and server.

💡 Pro Tip: Back answers with examples or a small snippet, and relate them to projects you’ve built. Be ready to explain trade-offs between technologies.

Few common problems with lot of resumes:

1. 𝐈𝐫𝐫𝐞𝐥𝐞𝐯𝐚𝐧𝐭 𝐢𝐧𝐟𝐨𝐫𝐦𝐚𝐭𝐢𝐨𝐧.
I understand that there are a lot of achievements that we are personally proud of (things like represented school/clg in XYZ competition or school head/class head etc), but not all of them are relevant to technical roles. As a fresher, try to focus more on technical achievements rather than managerial ones.

2. 𝐋𝐚𝐜𝐤 𝐨𝐟 𝐪𝐮𝐚𝐥𝐢𝐭𝐲 𝐩𝐫𝐨𝐣𝐞𝐜𝐭𝐬.
Many resumes have the same common projects, such as:
Creating just the front-end using HTML and CSS and redirecting all the work to an open-source API (e.g., weather prediction and recipe suggestion apps).

Most common projects are: -
Tic-tac-toe game.
Sorting algorithms visualizers.
To-do application.
Movie listing.

The codes for these projects are often copied and pasted from GitHub repositories.

Projects are like a bounty. If you are prepared well and have quality projects in your resume, you can set the tempo of the interview. It is one of the few questions that you will almost certainly be asked in the interview.

I don't understand why we can spend 2 years preparing for data structures and algorithms (DSA) and competitive programming (CP), but not even 2 weeks to create quality projects.
Even if your resume passes the applicant tracking system (ATS) and recruiter's screening, weak projects can still lead to your rejection in interviews. And this is completely in your hands.

I feel that this topic needs a lot more discussion about the type and quality of projects that one needs. Let me know if you want a dedicated post on this.

3. 𝐋𝐚𝐜𝐤 𝐨𝐟 𝐪𝐮𝐚𝐧𝐭𝐢𝐭𝐚𝐭𝐢𝐯𝐞 𝐝𝐚𝐭𝐚.
For technical roles, adding quantitative data has a big impact.
For example, instead of saying "I wrote unit tests for service X and reduced the latency of service Y by caching," you can say "I wrote unit tests and increased the code coverage from 80% to 95% of service X and reduced latency from 100 milliseconds to 50 milliseconds of service Y."
