Well, these two are somehow overlapping careers but there surely is a difference between them. The UI Developer and UX developer work as skin and organs in a body. The UI developer is in charge of visual design with design elements that help a user in navigation. On the other hand, UX Developer is responsible for the quality of the interaction a user has with the product. If your product is looking perfect but does not perform as per the instruction then it’s a bad UX issue while if the product is working fine but does not look appealing to the consumer, it’s bad UI.

This is one of the major misconceptions that both of these jobs are the same. Even a few people from the IT industry think the same too. The basic task for UI developers is to make a website user-friendly. They mostly work on Adobe Illustrator or such designing software. Since the job involves designing graphics, Illustrator is one of the popular tools used by UI Developers.
11. Can You Describe Your Normal Design Process?
The basic thing to start with is the brief and what exactly the client is looking for. This helps in the delivery of the design. Few clients are very specific in what exactly they want the design to look like while others have few ideas to discuss. I also incorporate both negative and positive feedback in the design via feedback forms. After this process, the next step is to create thumbnails and wireframes for the pages. During this, I share designed assets throughout the process to get quick feedback from the client’s side and incorporate their next feedback. If approved, I test the pages on the dummy website. If all is smooth, the website can go live at that time.
12. If My Website Was Slow, How Would You Diagnose The Problem And Fix It?
13. Name Three Ways To Reduce A Page’s Load Time.
To reduce the page’s load time, I would first reduce the image sizes used on the website. Later, I would reduce the redirects on the website and then eliminate unnecessary widgets used on a website. If still, the problem persists then deep cleaning along with page analysis of every website page would be required.
14. What Kind Of Skills Do You Think Are Crucial For A Successful UI Developer?
I believe in a combination of skillset for the successful UI developer. The success of a UI developer is dependent on visual design a skill that includes interactive elements, copywriting, animation, prototyping platforms, and SEO and site analytics. Additional skills should be Photoshop, HTML, and CSS for the smooth operation of the website.
15. How Many Types Of Heading Does An HTML Contain?
There are 6 types of headings in HTML that is defined with <h1> to <h6>. Each one of them displays a different text size starting from <h1> to be the largest and <h6> to be the smallest of all. H1 is one of the important levels while H6 is the least necessary one. The different headings indicate the start of a new section on the content page. If any heading level is skipped, it gets confusing for the users and should be avoided. For example, it is not a good practice if H4 is followed by H2 because it disturbs the overall look of the page but you can skip levels when closing the subsection. On the website, there should not be any empty heading because it confuses technology. All pages should start with H1 as a heading but there are exceptions depending on the website.
16. What Are A Few Recommendations In Headings From A UI Developer?
First of all, all caps should be avoided for any website. This can create issues for assistive technology users. Second, the Overuse of headings should be avoided too. The main purpose of the heading is to give structure to the content and should not be used for site titles.
Third, long headings should be avoided. The ideal size for heading should be less than 100 characters. If they are long, it again creates issues for assistive technology users.
17. What Is A Responsive Website?
Any responsive website should fit perfectly in all screen resolution that includes desktop, tablet, and a variety of mobile phone screens.
19. Which Are The Two Methods Used For Cross-Domain Ajax Calls?
If the data has to be transferred between security domains two or even more, there are 2 ways i.e. JSONP that works on legacy browsers and CORS that works with HTTP web browsers.
20. How Do You Deal With Negative User Feedback?
Feedback should be entertained even if they are negative. It helps in achieving a smooth website for a user to enjoy. A good way to tackle that negative feedback is to investigate with the users. Detailed information from the user is important. Sometimes a non-responsive page means that there is a coding problem on several operating systems. Simply revise and improve the coding and resubmit the data. Once done, you should again get in touch with the viewers who gave negative feedback. They will surely enjoy the improved version.
21. How Do You Debug A Page And What Common Tools Are Used By UI Developer
Chrome Dec, W3c validator, and Firebug are a few tools used for debugging a page that is having an issue.
22. Does HTML Need A Compiler?
