Top 30 Web Development Interview Questions and Answers in 2024

Interviews can be daunting, and if you are unprepared, you may become overwhelmed and lose confidence in front of the interviewer. Therefore, to help you with the interview, we have compiled 30 common interview questions and answers for web development.

1. What Exactly Is Web Development?

Web Development is a combination of the words Web (refers to web pages, websites, or anything we can access over the internet) and Development (the act of building such applications from scratch). It comprises creating and upkeep websites and web-based applications such as social networking sites, online e-commerce sites, and many more. This procedure entails developing a website that looks fantastic, performs smoothly, and provides a pleasant user experience. This process includes web design, publishing, development, and database management. Web developers sometimes called “devs,” carry out these jobs utilizing various coding languages.

2. What Are The Primary Duties Of Web Development Professionals?

As a web developer, my primary duties include:

  • Program test and debug each web application
  • Design, development, testing, and deployment of web applications.
  • Uploading websites to a server and registering them with various search engines
  • Develop web projects in collaboration with other designers and coders.
  • Fix bugs, perform troubleshooting, and resolve issues
  • Under a system breakdown, undertake regular testing and develop backup strategies.
  • Develop suitable code structures to address particular tasks.
  • Contribute to the upkeep and maintenance of websites.
  • Code owner during staging, development, testing, and production.

3. Why Do You Want This Position?

During my internship, I was responsible for maintaining the HTML of a Word Press blog, which stoked the fire of my desire to one day become a web developer. Front-end development became an obsession of mine. In addition, I wanted to become a full-stack developer because the functioning of the company’s website was driving me crazy and frustrating. My enthusiasm for programming has only increased over the years, and I am now equipped with the knowledge and skills necessary to tackle even the most challenging problems that arise in the field. I feel that working for your organization will provide me with additional opportunities to improve my skills in this field, and I look forward to taking on these new responsibilities.

4. Tell Me Briefly About Your Experience As Web Development Professional.

I’ve been a junior web developer for the past two years. During these two years, I’ve learned a lot by assisting senior developers in brainstorming ways to suit customers’ needs. This includes developing an action plan to fulfill the client’s website requirements. I’ve also developed coding languages such as CSS, XML, HTML, and JavaScript to design and develop applications based on customer standards. I would work with graphic design and marketing teams to create branding and web design materials. Using my expertise and talents, I will develop code software per your company’s standards, define and offer web solutions, and enforce network security.

5. What Programming Languages Have You Worked With Before?

While in my prior position, I worked with HTML, CSS, PHP, and SQL. I also used JavaScript. I would say that my knowledge of PHP and SQL is at the beginner’s level, but I have a strong command of JavaScript, HTML, and CSS because I was taught how to use those languages in school. I am a quick learner; therefore, if you use any other language, I would be pleased to learn it or further expand my skills in that language.

6. Why Did You Decide To Become A Web Development Professional As A Profession?

Five years ago, I started as a copywriter and loved watching my work’s positive effects on my clients’ websites. I decided to go into web development because I wanted to have a more significant impact on the outcomes for my clients. When I joined my last web development team, I knew I had made the proper choice because I was having a great time executing the work I was assigned in school.

7. Have You Ever Had A Client That Wasn’t Satisfied With Your Work? Why Did This Happen?

Yes, I had a client dissatisfied with the color scheme we had jointly chosen for her website. I reassured her it wouldn’t take long to fix and helped her choose a color she liked from various samples. I changed the website with her new color scheme, and everything worked well.

8. Just What Can Be Done To Speed Up The Loading Of A Web Page?

Multiple techniques exist for speeding up the loading of websites. The first things I do are compress images, consolidate and minify CSS, JavaScript, and HTML, and clean up the code. Then, I’ll use Google’s PageSpeed Insights to see how quickly the site loads and adjust accordingly.

9. If You Had To Choose Between HTTP 2.0 And HTTP 1.1, Which Would You Use?

HTTP 2.0 is the only protocol I use and advocate for, as it is much easier to work with and considerably quicker than HTTP 1.1. With HTTP 2.0, your site will load faster, use less bandwidth, communicate better with browsers, and increase search engine rankings. To sum up, the efficiency of online applications is vastly enhanced with HTTP 2.0.

10. Explain The Qualities That Set You Apart As A Competent Web Development Professional.

I believe my ability to be creative is one of my most valuable qualities. Because there are currently so many online apps available, it is crucial to assist clients in standing out from the crowd, which is why it is necessary to design a creative website. I am a skilled web developer because of my originality and my proficiency with computer code.

11. What Was The Most Difficult Web Development Project You’ve Ever Worked On? So What Happened?

One of the most challenging web development projects I’ve worked on was for a client who wanted their website to include a simple 8-bit game on one of the pages. I had to create the game from scratch. I don’t have much experience in software creation, but the client insisted, and I wanted to provide them with the website of their dreams. I could input the game and the rest of the design components the client sought, even though it was a challenging learning process.

12. Which Content Management Systems Have You Had Previous Experience Working With?

WordPress, Drupal, Joomla, and Magento were some of the tools I employed in my former employment. Because of the many configuration options available, WordPress is my go-to choice for a content management system. Ten years ago, as a beginner, I started using WordPress. Since then, I’ve worked my way up to coding and have created a wide variety of websites utilizing the WordPress platform. Despite this, I am eager to become proficient in using any content management system.

13. In Your Opinion, As A Web Development Professional, What Are The Distinctions Between Designing A Website For Mobile And Developing A Website For Desktop?

How a user engages with a mobile website vs. a desktop website is one of the most significant distinctions between the two approaches to website development. Mobile websites, for instance, need to include links that users can touch, but desktop websites need to have ones that users can click. Similarly, mobile websites need to include dropdown menus that are easier to use because the area available to the user to navigate on their phone is far less. Last but not least, the website is shown in a distinct orientation on each platform. Because customers will view mobile websites on their phones in a vertical orientation, they need to have a pleasing appearance and be functional in this orientation. Desktop websites are displayed in landscape mode, providing significantly more navigation and design space.

14. What Kind Of Workplace Do You Prefer?

I have a lot of fun being part of a web development team that works in an open environment. Because I prefer to talk to my coworkers about issues I’m experiencing or get their feedback on my work, it’s important to me that we have a space open to everyone and that we work closely together. On the other hand, I am pretty adaptable, so it won’t be difficult for me to adjust to any setting.

15. How Do You Stay Abreast Of Industry Developments And Trends?

Following a handful of online publications allows me to be abreast of developments in my field. Regarding publications geared toward web and app developers, I frequently turn to Smashing. They often publish articles on the latest industry developments and methods I may use in my work. In addition to learning from them, I take inspiration from the social media posts of more seasoned engineers like Jeff Atwood, Jeffrey Zeldman, and Brad Frost. It’s great to be able to use this time outside of work to read up on the latest developments in the world of web development.

16. When Presenting Your Web Development Services To Clients Who Have No Idea What You’re Talking About, How Can You Describe The Process To Them?

I avoid using jargon and stick to plain English while answering client inquiries about web development. When explaining my development approach to a client, I often show them examples from my portfolio or other works comparable to what they are requesting.

17. How Do You Make Sure Your Work Is Perfect?

Before releasing a website to the public, I use a pre-launch checklist to double-check for any mistakes. Job duties may involve testing links, including search engine optimization (SEO) keywords and content, and uploading images in their appropriate locations. After that, I double-check everything on the website myself and have a coworker look it over, too, to be sure.

18. Tell Me About A Time When You Messed Up In This Position And What You Learned From It.

When I was first starting in this field, the senior developer tasked me with building a website for one of our most important clients. My self-doubt was sparked by the realization that I was only a junior developer. With my self-assurance down, I lost sight of my progress. Two days later, the senior developer visited to see how far along I was, but I hadn’t even started the work yet. There wasn’t much time left, and he was getting increasingly frustrated. He insisted that I get to work on it immediately and do an excellent job. I was up against the wall, so I started building the website and had it up and running in three days. The senior programmer was pleased with the final result and expressed gratitude to me. What I took away from that experience was the importance of believing in one’s abilities. Since then, I’ve come to terms with the fact that I’ve created some really neat stuff that has benefited several businesses.

19. Please Elaborate On The Distinction Between Front-End And Back-End Development.

Front-end refers to the portion of a website that users can see and interact with, such as the graphical user interface (GUI) and the command line. Front-end also refers to the design of the website, as well as the navigation menus, texts, photographs, videos, and other content. On the other hand, the website’s backend is the portion of the site that users cannot see or interact with.

20. How Would You Rate Your Ability To Give A Presentation?

Since I have previously been in charge of sharing projects with clients and presenting our finished products to them, I am confident in presenting my work to others. I am comfortable giving presentations, and I have the impression that I can field inquiries and provide answers with relative ease.

21. Have You Ever Been Required To Address Unfavorable Feedback?

It’s true that when I started my job, I had some difficulties managing my time, and my boss was eventually forced to issue me a warning because of it. Even though the criticism initially made me angry, it didn’t take long to recognize that I had been returning projects late and disappointing customers. My manager was helpful, and we devised a plan to assist me in improving my organization. As a result, I am now better able to manage my time.

22. What Do You Consider To Be Some Of Your Most Impressive Soft Skills As A Web Development Professional?

I enjoy talking to people, and I believe I am an effective communicator with both internal corporate personnel and external customers. I find it helpful to be forthright about my intentions and the results I expect to achieve. Moreover, I am skilled at maintaining focus and completing tasks on time to keep my word.

23. Can You Explain The Benefits Of Using Git For Web Development Projects?

Git’s primary strength lies in the fact that it is a distributed version control system. When compared to other version control systems, its unique feature is the ability to monitor how files have evolved over time. This feature also lets you undo any previous edits you may have made to the file. With the Git system, it is not necessary to have a dedicated server to store all of a project’s file revisions.

24. How Can You Make UI Design Better?

As a first step, I’ll assess the app’s usability and how easy it is to get around. Then, I’ll focus on developing sequential tasks, such as a logical shopping progression, adding items to an online cart, and completing the purchase. By highlighting the final goals and the steps users need to take to achieve them, I will simplify the UI design and make it more accessible to a broad audience.

25. What Exactly Is The W3C, And Why Is Its Existence So Crucial?

As its name suggests, the World Wide Consortium (W3C) is an international group committed to improving and standardizing the World Wide Web. As a web developer, you should enforce these standards so that your site’s content displays correctly across all browsers, reaches as many people as possible, and provides the best possible user experience. Using CSS and XML that conforms to W3C standards ensures that all sites display and function consistently and boosts a site’s search engine rankings.

26. Can You Tell Me About Continuous Integration? Why Is It So Crucial During The Process Of Web Development?

The term “Continuous Integration” refers to a technique used in software development that involves frequent code integration into a central repository. This is something that developers do multiple times a day whenever they make changes to the codebase. We can then examine every one of these connections manually. Consistent integration and testing of each integration allows for faster error detection and easier localization. Due to the modest size of most codebase updates and integrations, tracking down the problematic modification is a simple and quick process. The benefits of using Continuous integrations are:

  • Lowers the risk – Regular code testing and deployment reduce the project’s risk level because we may now spot code defects and errors early.
  • Improved Communication – This increases transparency and collaboration among team members.
  • Improved Product Quality – Continuous Integration includes capabilities such as code review and quality detection, making identifying mistakes simple.
  • Waiting Time Has Been Decreased – The time it takes to design an application, integrate it, test it, and deploy it is significantly decreased.

27. What Would You Do To Improve Or Change An Existing Css Framework In A Company?

The type of CSS in use will determine the outcome. Changing the look of a semantic user interface or making enhancements to it might be challenging. This is because semantic UI is typically not well-suited to modifying existing project variables. I think it’s best if a business that uses Semantic UI switches to Bootstrap instead. For more straightforward, more simplified functionality, I like Bootstrap. It also supports variable overrides and markups with no semantic value.

28. Can You Name Steps In Web Development?

There are seven steps in web development, and the steps are:

  • Information Gathering: Purpose, Main Goals, and Target Audience – This stage, where you find out about things and do research, sets the standard for the next steps. At this point, the most important thing to do is to figure out what you want your website to be used for, what your main goals are, and who you want to visit your site. With this kind of website development questionnaire, you can figure out the best way to manage the project going forward.
  • Planning: Making a sitemap and a wireframe – At this point in making a website, the developer makes the information that lets a customer see how the whole site will look.
  • Page Layouts, Review, and the Approval Cycle in Design – Your website takes shape during the design phase. All of the visual content, like images, photos, and videos, is made at this step. Again, all the information gathered in the first step is very important. When designing, you should consider the customer and the people you want to reach.
  • Writing and Putting Together – Writing and putting together content for a website often happens simultaneously as other steps, and its importance can’t be overstated. At this step, you need to write down what you want to say to the people who visit your website and add calls to action. Content writing also involves making catchy headlines, editing, writing new text, compiling the existing text, etc., all of which takes time and work.
  • Coding – At this point, you can start working on the website itself. You should put the graphic elements made in the earlier stages together to make a website.
  • Testing, reviewing, and going live – Testing is probably the most often part of a process. Every single link needs to be checked to ensure none are broken.
  • Opinion monitoring and regular updates – With the site’s new feedback system, you’ll be able to find out if users are having any problems. In this case, the most important thing to do is to fix the problem as soon as possible.

29. As A Web Development Professional, How Would You Stop An Event Bubbling In A Software Program?

I understand that event bubbling causes both parent and child event elements to activate in a software system. An option to “block event propagation” in the code would be my first line of defense here. Suppose this doesn’t work to prevent the activation of the handler of the parent elements. In that case, I’d try issuing the ” event cancel bubble ” command to avoid the application elements from being activated.

30. What Exactly Is Cors? Why Is It Significant?

CORS is a browser technology that permits restricted access to resources outside a particular domain. It allows a web page from one domain to access a resource from another domain (a cross-domain request). It is a relaxation of the same-origin policy that current browsers use. JavaScript can only make calls to URLs that are of the same origin as the place where the script is running due to the same-origin policy implemented by XMLHttpRequest and get. Without CORS, websites are limited to accessing resources from the same origin via the same-origin policy.
