Front-end Developer Interview Questions

For the interview, the right questions need to be asked to assess the candidate’s knowledge of front-end development. These can be asked before or after giving a practical exam. Here are 7 sample front-end developer interview questions for interviewers and applicants:

1. How do you make sure that your website is user-friendly and accessible?

As an interviewer: You should know that front-end developers should have knowledge of designing an effective user experience for the website users. They need to have a grasp of what it takes to improve and strengthen the usability and accessibility of the software to its intended audience. The applicant’s answer will give you an insight into how well-rounded they are on standards and best practices.

As an applicant: You should be able to have the skills and knowledge in creating user-friendly sites in order to respond with an answer that you can support. You can answer this by talking about first-hand experience in creating accessible websites through implementations on different browsers and usage of screen reading tools. Additionally, working hand in hand with software designers have helped you gain such skills. This is the answer that you should go for when you actually have the experience to back it up.

2. What is the most interesting thing about coding?

As an interviewer: The applicant’s answer gives you an insight into their enthusiasm toward the craft. It could also give you an overview of what the applicant’s strength is when it comes to the different areas of front-end development.

As an applicant: Come up with an authentic answer especially one that you are sincerely interested in doing. You can start by sharing your favorite coding language or discuss the roundabouts of your life as a front-end developer. This could include how you deal with workloads, as well as the problems you’ve encountered, or how coding brings out your creativity and skills to life.

3. Site a technical challenge that you have encountered and what did you do to resolve it?

As an interviewer: For this question, you can evaluate the candidate’s problem-solving skills. It is important that they give a structured answer (preferably from experience) so you could assess how they can handle work issues or conflicts that may occur.

As an applicant: We all have different coping mechanisms when facing difficult decisions. In this situation, you may respond by answering the guide questions: Can I solve this on my own? If not, can I ask a fellow developer for help? If not, can I ask the whole team for help? And so on. Do not forget to cite your first-hand experience to validate your answer to a degree where it has been proven and tested.

4. Can you differentiate XHTML from HTML?

As an interviewer: Getting into the technical aspects of the interview is very crucial. By asking the right questions, you can assess how skilled and how knowledgeable they are. You can start by asking them to differentiate two topics from one another. This is just a simple question but it requires a concise but specific answer.

As an applicant: You should know that XHTML is just HTML but with the extra added power of the XML markup language to your website. This enables you to gauge more control and accessibility to your webpage. Furthermore, you should be ready to answer this type of question as field experts may ask you one or two.

5. What are pseudo-elements (in CSS) and what are they used for?

As an interviewer: For field experts who will do the interview, asking difficult questions may come to mind. However, asking the basics are just as important. This question asks for a definition and usage of a keyword but you may tweak it by replacing it with another term or syntax used in coding.

As an applicant: Knowing the definitions of keywords and usage will also come in very handy. For this type of question, answer with the definition and how it can be used. It would be better if you cite an example along with your answer. To answer the question, pseudo-elements are keywords added to a selector that allows you to implement styles on a specific part of a selected element.

6. How do you properly structure your CSS and JavaScript?

As an interviewer: By asking this question, you will get an insight as to how a front-end developer is well-rounded with coding standards that apply in implementation processes. Front-end developers are often faced with working on code created by previous developers.

As an applicant: By now, you should know how to properly structure your CSS and JavaScript. Also, you may have experienced applying the coding standards from your previous job. If you are experienced enough, identify which structure works best for you. If not, explain how you are willing to learn these standards and apply them the best way you can.

7. Where do you see yourself in the company after your first year?

As an interviewer: An employee who has the skills and knowledge to take on the job makes an ideal candidate. But what makes it even better is the employee’s vision and persistence to contribute to the growth of the company.

As an applicant: As a developer, you will not only leave codes for future developers. You will also leave a legacy as you hop from one company to another. It should be your goal to enhance your skills for you to grow with the company. You may answer this question, not with your head, but by heart and sincerity. “In a year, I see myself as a person with better capabilities in a company that I have helped become better.”

Overall, answers will vary based on the setting and your experience. However, it should be a golden rule to always respond honestly with answers you can support with your knowledge, skills, experience, and even the willingness to work.
