Interview Questions for Web Developers

During the interview session, a web development company’s hiring manager will try to find many qualities through the web developer interview questions. The most common questions will assess whether the candidate is enthusiastic and has the essential qualifications and a good personality to grow in this sector or not.

The responsibility of a web developer circles around programming the code that provides the website with the functions to work. They create websites that are "easy to navigate" or simple for visitors to browse.

Additionally, they create website features like forms to collect emails or to send newsletters, paywalls to collect payment information, and thank-you messages for patrons.

What Does a Web Developer Do?

The field of web development requires computer geniuses who are competent enough to operate web servers. To work efficiently, they need to have a skill set in web applications and software programs, including JavaScript (JS), C++, HTML or Hypertext Markup Language, and Ruby on Rails.

Many web developers work on projects for companies, clients, or short businesses as freelancers. Nevertheless, most multinational companies prefer to have their own web development team to monitor the company’s business. The interview questions will change patterns depending on where you are looking to work.

The assigned work of a web developer determines the job's responsibility. In the current job market, three web developers are in the highest demand.

  1. Client-side scripting: coding for the web browser (typically designing a website).
  2. Server-side scripting: coding for the website to operate smoothly and efficiently (working on web power and server).
  3. Database technology: inserting tools to run the website effectively and smoothly without any glitches.

Depending on the work pattern of the web design, the web developer may need to focus on the following function:

1. Back-End Development

Creating and maintaining technological components that empower the website’s user-facing side is the requirement for these web developers. The work of a back-end developer begins after front-end development is done.

2. Front-End Development

Everything a visitor sees, clicks, and scrolls on a website is the result of front-end development. Designing the frameworks and scripts, markup languages integration, and developing the overall environment to make a website user-friendly is the job responsibility of a front-end web developer.

3. JavaScript development

The work of a web developer doesn’t end right after a website goes public. From the moment it goes public, the JavaScript developers work with the JS to enhance and modify the loopholes.

4. Full Stack Development

Undertakes best practices and strategies to guide and control the overall web development process. Their work is to oversee the big picture and take care of both sides of a website-the client side and the user side.

5. Additional work includes

  • Web application testing
  • Updating the functioning of the website
  • Meeting clients to discuss the design of the website
  • Incorporating multimedia into a website
  • Creating more appealing and exciting sights for the viewers
  • Creating navigation menus and user interfaces
  • Solving issues with user experience or performance
  • Cooperating with stakeholders, designers, and developers
  • Composing and reviewing website code, usually in HTML, XML, or JavaScript

Basic Skills Needed for a Web Developer Job

The hiring manager may ask you about your educational requirements. 

If you are an aspiring web developer, you need to have the academic requirements and certificates to prove that you have the potential and have finished your Bachelor’s Degree in either web development or computer science. After that, you can apply for entry-level jobs at companies seeking a web developer.

Depending on the type of work web developers want, they try to complete the certification courses with customized and significant courses about that skill. For example, HTML is a coding language that front-end code developers must learn. 

You will find some similar coding languages that web developers learn to level up their creative game. 

1. JavaScript

Creating websites that will run smoothly and efficiently on all kinds of devices is not an easy task. In order to design and control mobile app content and dynamic web pages, JavaScript is the scripting language that helps web developers. 

JavaScript libraries also include jQuery and React JS. They are known as pre-written codes. Learning about these languages can help in the coding process. 


The markup language named HTML helps web designers with formatting and rearranging web pages. 

3. CSS

After designing the webpage, CSS is used by the developers to add more colors, fonts, and styles.

Soft Skills Requirements:

Your technical knowledge will help you to develop a website, but the soft skills in your character will assist you in working with your team. Continue reading to know the skills.

4. Being able to work in a Team

In some specific cases or more significant projects, a team of multiple developers works together to build a website. You can have different points of view to share with your teammates when you have a difference of opinion. But working in a team is the only way to complete beautiful projects.

5. Keeping your mind open for new ideas

If you cannot keep your mind open and free, you will never be able to grab what your clients want from you. Take ideas from around you and your team, listen to your clients, and learn what developments they want or problems they face to improve your work.

6. Having Patience

While working with a client who wants your service but has less knowledge about the website languages, you may need to make them understand. To make people understand the technical features, you must have patience.

7. Other skills in short

  • Communicate effectively with your teammates
  • Show empathy to your team members
  • Admit your mistakes and learn from them
  • Be attentive to your time management
  • Be approachable and helpful with setting meeting times
  • Explore more about your creativity- study fiction, arts and crafts
  • Solving new problems every day is just a part of your job
