What is the importance of the User Interface when developing applications?

Since the User Interface (UI) is one of the most critical parts of any application, you can expect many questions about this topic. As a developer, you should be able to address these based on your education and experience. Be sure to discuss the business benefits of a good UI design since this is important to companies developing commercial applications.

"The User Interface, or UI, is probably the most important feature of a well-designed application. No matter how good an application functions, a bad UI will make it difficult to use and frustrate the users. The key to developing a good UI is to understand how users will interact with the application and what platforms they will use it on. Making the UI responsive so it will have the same look and feel across various platforms is also important. Finally, the UI should be tested with actual users to confirm that your assumptions are correct and to address any issues they identify before the application is released."
