Common Web Developer Interview Questions And Answers
What are the responsibilities of a web developer?
A web developer needs to be well aware of their position within the web development process. You can learn more about a candidate’s support strategy and the jobs they will take on by asking them this question.
Suitable Answer: A web developer designs, develops, enhances, tests, and deploys web applications with the end goal of creating engaging and user-friendly site layouts and functions. A developer gathers and defines requirements, maintains websites, troubleshoots and fixes bugs, follows best practices, and collaborates with other teams.
What sparked your interest in web development?
Did the applicant grow up wanting to work as a web developer? They’re self-taught, right? Finding out a candidate’s motivation for choosing web development might reveal how passionate and dedicated they are to the field.
Suitable Answer: As a previous marketing coordinator, I frequently used an online tool to create and customize email campaigns. I found the drag-and-drop feature buggy and discovered that I could achieve the look I was going for if I edited the HTML instead. I became fascinated by the ability a web developer has to be imaginative, artistic, and technical while developing a product that benefits and inspires others.
Explain how you optimize and reduce web application load time.
A web page should load in under two seconds for about half of all visitors. To find out if a candidate is aware of the effect that page load time has on the user experience and how a web developer should evaluate data and monitor advancements to reduce the load time, ask them this question.
Suitable Answer: Although there are numerous techniques a web developer can use in reducing load time, I always rely on optimizing images, enabling browser caching, and minimizing HTTP requests. My go-to tool for evaluating site speed is Google PageSpeed Insights. In one instance, I successfully reduced page load time from 2.1 seconds to .7 seconds by solely enabling browser caching.
What are the differences between using HTTP/2 as opposed to HTTP 1.1?
You can get a sense of a candidate’s level of awareness and how their approaches will fit into the web developer role by finding out if they are aware of the primary advantages and differences of using HTTP/2.
Suitable Answer: HTTP/2 was designed to improve web application performance. A web developer can appreciate how it makes applications simpler and faster by reducing load times and improving communication between browsers and servers. I’m a strong advocate for using HTTP/2, as I’ve analyzed data and seen how HTTP/2 can decrease page load time by up to 20%.
What programming languages do you use?
How do you balance the strict requirements of your clients?
Unexpected difficulties may arise for a web developer, such as quick turnaround periods and overly ambitious clients. You can better grasp a candidate’s priorities and mental processes by learning how they respond to situations of this nature.
Suitable Answer: In balancing demanding requirements as a web developer, I take steps to fully understand what is expected of me, prioritize my tasks and keep an open line of communication with the client. Keeping a client pleased is a high priority, although I am not interested in producing buggy code and taking ineffective shortcuts to damage the final product. I keep the client informed of my progress and work efficiently to complete the task.
How well do you respond to criticism of your web development efforts? Give us an example, please
Websites and web applications are made for clients by web developers using coding languages. To achieve client satisfaction, this process typically necessitates numerous rounds of corrections in response to client criticisms. This inquiry aids interviewers in determining a candidate’s capacity for accepting constructive criticism. Additionally, it demonstrates how much importance a candidate has on client feedback and their capacity to promote their employer proficiently.
Suitable Answer: Through my years of experience as a web developer, I’ve learned how important constructive criticism is to deliver products that meet a client’s vision. When I was in an entry-level developer role, I worked on a web application project for an online store. I was proud of my work and felt I’d done everything I could to meet the original client criteria.
After two rounds of corrections, I realized that constructive feedback is a way for clients to refine their needs. Receiving constructive feedback also helped me hone my skills and learn more about the client to maximize future projects.
