10 important web developer interview questions to practise

Here are 10 interview questions for a web developer, including why interviewers ask them and ways to answer:

1. Explain your favourite web development project and how you completed it.

Interviewers ask this question to assess your web development skills. It helps them gain insights into projects you enjoy and your preferred methods for completing them. Identify an exciting project you worked on to keep the interviewer engaged in your response. Then, describe the web development process you followed from start to completion.

Example answer: "Creating a website for a toy company was an exciting project I completed at my last job. I enjoyed meeting the client and identified their needs. For this project, the objective was designing a functional website that appealed to children. I focused on the user interface and defined the scope, including the required web pages and features. Then, I worked on the sitemap and wireframe. Next, I developed visual elements that appeal to younger customers by using bright colours and cartoons. The entire process was rewarding because it enabled me to apply my creative skills."

2. How would you communicate progress on web development projects to clients?

Keeping clients informed about web development projects can help to build trust. By asking this question, interviewers want to evaluate your ability to provide excellent customer service. Discuss how you present the technical aspects of your work in simple language.

Example answer: "I feel it is important to maintain communication channels about important web development stages with clients. In my experience, communicating about the project's progress can ensure client satisfaction. I typically send emails to clients about the ongoing website or application. If they are available to review my work, I prepare interactive presentations that include graphs, charts and images. I also use simple words and analogies to explain technical concepts. For example, I often describe bootstrapping as the process of bending over and trying to lift yourself."

3. What specializations in web development interest you?

As a web developer, you can either specialize in front-end, back-end or full-stack development. While front-end developers focus on aspects a client can see, back-end developers work on servers, applications and databases. A full-stack developer performs the duties of both frontend and backend developers. This question helps an interviewer understand your strengths. They also ask it to decide on a suitable team for you.

Example answer: "Although I started my career as a front-end developer, I transitioned into full-stack web development two years ago. I enjoy working on websites and web applications from start to completion. From my review of the job description, I understand this role requires me to transition between front-end and back-end tasks, and I'm confident I have the required skill set."

4. Describe your ability to work as part of a team.

Depending on the project, company and role, you may work with other web developers, designers, content creators and project managers. Interviewers ask this question to evaluate your teamwork skills and experience working in a team.

Example answer: "I am a good team player who enjoys working in a collaborative environment. My last positions required me to meet with content creators and UI/UX designers regularly and I enjoyed implementing designs and including content with them. I also have experience working in a web development team, and I find it motivating to collaborate with professionals with similar interests."

5. What is the difference between HTTP and HTTPS?

This question helps an interviewer evaluate your knowledge of web development. HTTP and HTTPS are common transfer protocols you may encounter at work. Explain the difference clearly and consider providing examples.

Example answer: "HTTP stands for hypertext transfer protocol. In comparison, HTTPS standards for hypertext transfer protocol secure. HTTPS uses transport-layer security to encrypt regular HTTP requests and responses. You can tell the difference by examining a website's unique identifier for locating it on the internet, called the uniform resource locator (URL)."

6. What programming languages are you proficient in?

Writing computer codes is an important aspect of any web developer role. Show your competence by listing programming languages you are familiar with and providing examples of when you use each to convince hiring managers of your programming skills.

Example answer: "I enjoy writing computer codes in JavaScript, Python, PHP and Ruby. I am also proficient in Python, R and CSS. At my previous job, I built many websites using CSS, HTML and JavaScript. I also developed application programming interfaces (APIs) with Python and R. As a fast learner, I am eager to learn more programming languages and build my technology stack."

7. How would you make a slow website faster?

Slow web pages can be a challenge for users and an important task for web developers to overcome. By asking this question, you can show your understanding of website optimization techniques. Respond in simple language for your interviewer to understand how you make slow websites faster.

Example answer: "In my experience, there are various reasons a website might load slowly. I start by identifying the reason and developing effective solutions. For example, if the problem is due to bulky codes, I typically reduce the HTML, CSS and JavaScript codes I write. Similarly, if the problem is with the transfer protocol, I typically limit external HTTP. I also check whether I enabled Javascript and reduce the videos and images on the website."

8. How do you ensure websites and applications are accessible to users?

User experience is important to businesses because it determines the likelihood of a website visitor returning. It can also impact SEO rankings. The purpose of this question is to evaluate whether you understand how individuals access the internet and your desire to develop websites they can visit easily.

Example answer: "I understand visitors use various browsers and devices to access websites. I first identify all possible tools an individual may use. Then, I perform extensive testing to ensure consistency of user experience. I use software, such as screen-reading applications to confirm that the projects I complete are accessible to users from their browsers and devices."

9. Describe your debugging process.

While you may strive to write perfect computer codes for websites and applications, you typically have issues to resolve after the first draft. Debugging is the process of identifying and correcting errors. This question helps an interviewer understand your approach to correct possible errors you may make.

Example answer: "As an experienced web developer, I see computer programming errors as a learning opportunity. I start by reviewing each code line I write and checking relevant documentation on how to correct programming errors. When working on large projects where reviewing each line may be challenging, I automate the process using debugging tools. I also test the website after debugging to ensure it is functional."

10. How do you stay current with web development frameworks?

This question helps an interviewer assess your desire to improve your web developer skills and gain more experience. Even if there's an opportunity for training on the job, show your eagerness to become a better web developer.

Example answer: "Like other technology roles, I feel it is important to stay current with web development frameworks and tools. I subscribe to popular video-streaming websites, read blogs and listen to web development podcasts. Recently, I joined a networking channel for web developers and find learning and sharing my knowledge about web development fulfilling."

What to expect in a web developer interview

In web developer interviews, you can expect hiring managers to assess your career and qualifications. Depending on the company and role, the interviewer may ask you to write computer codes. You can prepare for general questions, such as inquiries about what motivates you as a web developer and why you chose this career path. Use these interviewers to showcase your enthusiasm for the job opportunity and outline your value as a web developer. You can prepare a mock interview with your friend, mentor, family member or career coach to improve your responses to possible questions.
