30 Best Interview Questions For App Developers

App development is a critical aspect of today’s mobile-led technological landscape. As smartphones have become an essential part of our lives, app developers play a key role in developing the apps that power these devices and facilitate many of everyone's favorite platforms. Because of this, the demand for mobile app development has skyrocketed, as well as the need for skilled app developers - whether they’re hired through nearshore staff augmentation or traditional hiring methods. With almost every 21st-century human relying on mobile apps for communication, entertainment, education, and eCommerce, it's important to have a good understanding of the skills and experience that make up a solid app developer, as well as the types of questions to ask when interviewing potential candidates. Today's article is all about app development, its benefits, why it is important to hire app developers, and the best interview questions for app developers.

What Is App Development?

App development involves creating software applications for mobile devices, like smartphones, tablets, and even smartwatches. The full process consists of designing, developing, testing, and deploying mobile apps. These mobile apps are designed to run on a variety of different platforms, including iOS, Android, and Windows, as well as Chrome devices. With app development expected to reach a revenue of $935 billion by the end of this year according to Statista, and smartphones becoming more and more omnipresent in our lives, it's safe to say this tech stack is here to stay.

Why Hire App Developers

Hiring app developers can be beneficial for businesses that want to create a mobile presence, as these are the IT professionals responsible for designing, coding, and testing apps. These are highly skilled developers that can help your company create mobile apps that meet the needs of your customers while also ensuring a secure and reliable user experience. Furthermore, if you decide to hire a nearshore developer for an extended period of time, app professionals can help you optimize any existing applications for an improved user experience and increased performance. Not to mention they can continuously refresh them to stay up-to-date with the latest trends in the industry! At the end of the day, app developers are a necessary hire if you want to develop efficient mobile applications and ensure the long-lasting digital success of your business.

Now, in order to hire a strong app developer, you need to understand how to best recruit them, from where to look for available candidates to the type of questions to ask during an initial interview. For starters, any solid app developer should have a solid understanding of coding languages such as Java, Swift, and Objective-C and experience with UI/UX design principles as well as platform-specific frameworks. This includes web services and APIs as well as data storage solutions such as SQLite, CoreData, and Realm - the ones more commonly used during mobile application development. Now, these are some of the things your future candidates should know about and have experience with. But how do you test their skills? The answer is through the right interview questions for app developers.
