8 Web Development Interview Questions And Answers

Consider the following eight web development interview questions and answers to model yours accordingly:

1. Describe your best web development project and the steps you took to complete it.

Interviewers use this question to gauge your proficiency in web development. It enables them to learn more about the kinds of projects you find enjoyable and your default techniques for finishing them. To keep the interviewer interested in your response, mention an interesting or unique project you have worked on recently. Then, briefly discuss the key detail of the web development stages you followed.

Example: "In my last position, I worked on an exciting project involving the creation of a website for a toy business. I thoroughly loved meeting the client and assessing their requirements. As the purpose was to create a child-friendly, easy-to-use website. I prioritised the user interface and determined the project's scope, which included the required web pages and functionality. I then developed the wireframes and sitemap. Using vibrant colours and cartoons, I then created aesthetic components that appeal to younger consumers. The entire procedure was satisfying as it allowed me to utilise my creative design abilities."

2. How do you update clients on the status of their web development projects?

Keeping clients informed of web development projects helps foster confidence. This question assesses your ability to give exceptional customer service. Discuss how you simplify the discussion about the technical component of the project to the non-technical client.

Example: "I believe it is essential to have regular communication with clients regarding crucial web development phases. My experience has shown that reporting the project's progress can increase client satisfaction. I frequently communicate with clients via email or other convenient means regarding the ongoing website or application. If they are available to evaluate my work, I provide interactive presentations with graphs, charts and photographs whenever necessary. I also employ simple language and analogies to illustrate complex subjects to ensure clients understand it effectively."

3. What specialisations in web development interest you most?

You can specialise in front-end, back-end or full-stack development as a web developer. Back-end developers focus on servers, apps and databases, whereas front-end developers concentrate on client-facing features. This question assists the interviewer in determining your strengths and helps determine the best team for you.

Example: "I began my work as a front-end developer, but two years ago I switched to full-stack web development. I am passionate about building websites and online apps through their development cycle using my creative skills and technical knowledge. I realise from reviewing the job description that this position requires me to switch between front-end and back-end responsibilities and I am confident that I possess the necessary skill sets to do this successfully."

4. Tell us about your ability to work as a part of a team.

As a web developer, you might collaborate with other developers, designers and project managers. This question helps the interviewer assess how well you collaborate with others and how much teamwork experience you have. While answering such a question, consider including a few examples from your past role.

Example: "I believe I am a fantastic team player and thrive working in a cooperative setting. My previous jobs required me to meet and interact with content writers and graphic designers regularly and enjoyed putting designs into practice and incorporating material with them. I have had experience working in a web development team and I enjoy collaborating with other experts working on the same project."

5. In which scripting and programming languages are you proficient?

Almost all web developers' job requires them to write code. List the programming languages you are well-versed in and give instances of when you have used each to convince the interviewer of your programming abilities. You can also mention the languages you are currently learning.

Example: "JavaScript, Python, PHP and Ruby are some of my favourite programming languages. I am also skilled in R and Cascading Style Sheets (CSS). I created many websites utilising CSS, HyperText Markup Language (HTML) and JavaScript in my former job. With Python and R, I also created application programming interfaces (APIs). I am also excited to grow my technology abilities and learn other programming languages."

6. What steps do you take to improve the speed of an existing website?

Users may find it difficult to navigate slow online pages and web developers require working hard to solve this problem. You can demonstrate your knowledge of website optimisation approaches by answering this question. To help your interviewer understand how you can speed up slow websites, respond in simple language.

Example: "Several factors, in my experience, can cause a website to load slowly. I begin by determining the cause and coming up with workable solutions. For instance, I often write smaller HTML, CSS and JavaScript codes when the issue is because of bulky codes. Similar to this, I often test by restricting external HTTP if the transfer protocol is the issue. I also make sure that CSS and JavaScript minifications are working and compress the website's video and images."

7. How do you consider search engine optimisation (SEO), performance, user experience (UX) and security while developing a web application?

This is one of the interesting questions the interviewer often asks. It requires you to explain how to decide aspects of a project based on the organisation's type and requirements. In your answer, mention how your project process ensures these components get adequate attention.

Example: "As search engines are one of the primary tools that people use to find information on the internet, I optimise utilising the relevant keywords for the website meta information, images and ALT tags. To help ensure better performance, I make sure to not repeat the code. I also run benchmark tests to find the scopes for potential performance improvements. I also implement server and client-side caching to improve load times.

While designing the web app, I follow the design principles to ensure people find it easy to use. I try to use the design cues to make the website or app intuitive for a new user. App security is crucial and to ensure it, I keep myself updated on current security trends and regularly update the application and associated libraries to patch security gaps."

8. What are asynchronous JavaScript and XML (AJAX) and its benefits?

AJAX is a relatively new technology which has great potential to improve user experiences. Such questions can help the interviewer find if you are aware of such performance improvement techniques. You may briefly explain AJAX and how it works and then mention some of its key benefits.

Example: "AJAX allows different apps to transfer data asynchronously to and from a server without reloading the web page. It ensures automatically updating certain portions of the page without requiring a full page reload. We can deploy anywhere AJAX in a web application where the app retrieves or store information in small chunks. This technology facilitates the development of interactive and efficient online applications. Some of the major benefits of AJAX are that it can increase web performance and usability, enable asynchronous calls to a web server, improve callback performance and also help make web pages user-friendly."
