The following are some samples of web development interview questions and answers:

What would you call a Web Developer's job description? What components of the job are the most significant, and why?
Depending on the job description and whether or whether a hiring manager is searching for back-end specialists or front-end web developers, the particular position of a Web Developer will vary substantially. Most Web Developer careers, however, will eventually include the following responsibilities:

Working with clients or company stakeholders directly to understand their needs and expectations

Web application design, development, programming, testing, upgrading, and debugging

To design, create, and deploy significant online projects, I collaborate with designers, other developers, UX specialists, sales and marketing teams, and other stakeholders.

Assist with the upkeep of websites, online applications, and other web-based goods. Those are only the most basic routine web development chores; to get more precise, go back to the job description and make sure your response addresses all of the position's primary responsibilities and competencies.

What programming languages have you worked with before?

The recruiting manager wants to know that you've worked with a variety of programming languages and, most crucially, that you're familiar with the company's preferred coding language. To answer this web developer interview question, go over the job description again and prioritise any coding languages that are required. If you're more familiar with some languages than others, be honest about it. For example, you might have used HTML, CSS, PHP, and JavaScript extensively in your current role, but you've only scratched the surface of Ruby or SQL. Giving the hiring manager an idea of the specific applications you have for each programming language is also a good idea.

Questions to Ask in a Web Development Interview: Technical Questions

Your web development knowledge will be put to the test with technical interview questions. You must explain how you would apply your talents to specific issues or tasks in these questions.

The following are some samples of technical Web Developer interview questions:

Cleaning the web code, eliminating redirection, caching, picking smaller pictures or reducing image size, deleting superfluous widgets, and reducing lookups are all examples of strategies to improve page load time.
