Web Developer Interview Questions & Answers
10 questions employers ask web developers, and what a strong answer looks like.
Expect questions about technical knowledge (such as html, css and javascript), safety and how you work with people. Use the STAR method (Situation, Task, Action, Result) and practice out loud. Below are 10 common questions with guidance on strong answers.
Web Developer-specific questions
1. Walk me through a project in your portfolio.
Explain the problem, your decisions, challenges and results.
2. How do you make a site fast?
Mention image optimization, caching, minimizing JavaScript and Core Web Vitals.
3. How do you ensure accessibility?
Describe semantic HTML, labels, keyboard support and testing.
4. How do you handle a bug you can’t figure out?
Describe isolating, reproducing, researching and asking for help.
5. Tell me about working with a designer or client.
Show collaboration and communication.
General and behavioral questions
6. Why do you want to be a web developer?
Connect a real motivation to the work itself. Mention what drew you to web developers’ day-to-day tasks (for example, build web pages and applications from designs and requirements) and show you understand the challenges as well as the rewards.
7. Tell me about yourself.
Give a 60–90 second summary: your background, the training or experience that prepared you for this role, and why this employer. Keep it relevant to web developer work.
8. Describe a time you made a mistake. What did you do?
Pick a real, low-stakes example. Explain how you owned it, fixed it and changed your process. Employers want honesty and learning, not perfection.
9. How do you handle stress or a heavy workload?
Describe a specific system: prioritizing safety-critical work first, communicating early when you are behind, and staying organized. A short example from school or work makes it credible.
10. What questions do you have for us?
Always ask two or three: what training looks like for new hires, how success is measured in the first 90 days, and what the team likes most about working there.
Speak the language
Hiring managers notice when candidates use the right terms naturally. Review these before your interview: HTML, CSS, JavaScript, Responsive design, Front end, Back end, API, Framework. See the full glossary.
