General interview questions 2024

When you are interviewed for a job as a UI developer, your interviewer may first ask you general interview questions. As an example:

• Tell me about yourself.
• Where do you see yourself in five years? In 10 years?
• What makes you think you would be a good fit for this company?
• What do you love most about being a UI developer?
• What are your greatest strengths and weaknesses as a UI developer?

Your interviewer may also ask you general questions connected to your UI role. For example:

• How do XHTML, HTML4 and HTML5 differ?
• What does the term “semantic HTML” mean?
• Why are HTML, CSS and JavaScript referred to as front-end technologies?
• What does web accessibility mean?
• Discuss the position property in CSS and how it functions.
• How can you test a website’s performance?
• What is an Ajax Request?
• What is jQuery?

Sample UI developer interview questions 2024 and answers

During your interview, you may be asked to share your professional experience with specific tasks and scenarios. The STAR approach can be used to explain the problem, clarify the work at hand, outline the activities you performed, and reveal the results of your efforts.

Here are some detailed questions you might be asked in a UI developer interview:

1. Can you describe your normal design process?

This is a comprehensive topic, and your response may assist the interviewer in determining your suitability for any established web design team. Your design method may differ from that of other UI designers, but the interviewer may want to know if your procedures are meaningfully similar to those of the organization. When answering this question, be honest about what makes your design approach unique, but also demonstrate that you are capable of and ready to follow standard processes.

I begin my design process by asking my clients what they want their site or application to look like or how they want their users to feel. Some of my clients may have some idea of how they want their website to look and feel while others give me specific details and data related to the purpose of their websites I can use to guide my design.

My next step is to review visitor feedback. I may create and send out my own feedback forms or use those my clients already collected. I use both positive and negative feedback to inform my design. After this research, I create thumbnails and digital wireframes for website pages. I show my clients the designs and assets I create throughout the process to get quick feedback and make any changes as soon as possible. Then, I test the pages on a practice website. If the pages look and feel great, they can go live.

2. Describe a normal working day for a UI designer.

If your interviewer asks you this question, they may be interested in learning more about your ability to operate as part of a team. Consider what you regularly do as a UI designer on a daily basis, such as what your regular tasks are, how you do temporary jobs, and how you communicate with coworkers, supervisors, and clients.

Usually, my day starts with a team meeting. We discuss our progress with certain aspects of website improvement and what we need to do to finish our tasks for the day or week. After our discussion, we spend an hour or two inspecting our code and testing it in a “sandbox,” or test website, before going live, if our coding and asset creation is finished that day.

Throughout the day, I may receive messages from my supervisors and any clients who want updates on my projects. I make sure to promptly respond to each. I also spend some extra time I have each day reading up on any new developments on the UI industry and taking notes so I can discuss the changes with my team the next time we meet.

3. If my website was slow, how would you diagnose the problem and fix it?

This is another question that helps your interviewer to assess your method, but this time you can discuss your troubleshooting knowledge. When answering this question, walk the interviewer through the steps you’d take to determine out what’s slowing down webpages and what you’d do to speed them up.

I would inspect various factors on your website. One thing I would do is use a link analysis tool to see if there are any dead links on the website. I would also check the coding on various pages of the site. One solution to the latter problem is to link similar pages to one CSS sheet and simplify the coding.

Another thing I might do is move the JavaScript coding near the bottom of a page’s HTML document. This allows the page to show before all JavaScript coding is downloaded. Additionally, I would check the servers of the website. If allowed, I would change the distribution of the website to a content delivery network. This allows users to access the website via a server that is closer to their locations. After all this, I will again test the speeds of the website.

4. What do you like the most about UI design?

This question allows you to discuss what motivates you to do your job. Consider talking about the aspects of your prior job that you liked. For an even more effective response, underline the challenges you anticipate in this new role.

You may hear this often, but my favorite part of UI design is when a system I have worked on is finally in the hands of users. I like to see how users interact with the websites and applications and to know that my hard work has made life easier for them in some way. Now, if a user experiences a problem with the system or website I worked on, that might mean that I have made a mistake. However, I relish the opportunity to take in user feedback and improve the system or website.

5. How do you deal with negative user feedback?

All UI designers will receive bad feedback; what matters is what you do with that feedback. You can apply the STAR technique with this question. Discuss a bad feedback experience you had and what you did to rectify the situation.

One time, I worked on a free smartphone game app that required users to tap the screen with precise timing, but three out of five users left comments saying that the app was nonresponsive for them. Most of them left a rating of one or two stars.

After corresponding with some users and having them investigate if there were outside issues, like magnets, that made their screens unresponsive on their end, I checked the coding of my app and realized that it was too large for certain phone operating systems. I revised the coding and resubmitted the app. The users I talked to all noticed a vast improvement in the system.

6. Can you describe any other projects you have worked on 2024?

The inquiry concerning user input may lead to another about your experience as a user interface designer. This is your chance to discuss how you collaborated with a team on a larger project. Consider talking about a time when you had to overcome a hurdle and detail what you did to get positive results.

I was once on a four-person team whose job was to overhaul the website of an accomplished author and motivational speaker. The website had a lot of broken links, much of the text and assets were relegated to tables, there was a lot of colorful text and the site navigation was not intuitive. I worked with a writer, a graphic designer and an IT person to improve over 150 pages of content.

After two months, I was able to redesign each page of the site, moving the navigation from the side to the top of each page. I even included a site map. Six months later, the website experienced more than triple its normal traffic. The owner of the website was so impressed with the design of the website that he recommended me to one of his friends.

7. Can you describe a time where you had difficulties while working on a team?

If you’re applying for a job that requires teamwork, your interviewer may want to know what teamwork abilities you have and how you’ve used them in the past. Discuss another example in which you worked in a team but where the team encountered difficulties working together. Consider emphasizing how you collaborated on solutions, resolving problems, or increased productivity.

I once worked on a remote four-person team for a software startup. One of the challenges of working with the team was figuring out how to communicate despite different time zones. To get around this problem, we used conferencing software and scheduled one-on-one meetings.

One day, I even asked the team leader, who was often unapproachable, what he thought about the conferencing software’s user interface. That led to a long discussion during which we talked about the tasks at hand for our team. That week, we figured out how to break up the workload among teammates, based on our strengths and the times we would likely upload our work. After a month, we were able to submit a product that users tested and provided feedback for. Through this experience, I learned more about correspondence and how to apply user feedback to my work.
