How to hire a Kotlin developer? Skills to look for, interview questions, and more
Kotlin is a high-level programming language that combines features of object-oriented and functional programming paradigms. Like Java, the source code of Kotlin is first converted to bytecode and executed on a Java Virtual Machine (JVM), independent of an external environment or an external operating system.
Professional Kotlin developers are experienced in functional programming, web service concepts and are familiar with Android libraries. They work in all phases of the development cycle, test and amend features while contributing immensely to the organizational goals. But hiring a Kotlin developer for your business can be a cumbersome task. It may be one of the most in-demand skills in the market presently, yet getting an exceptional Kotlin developer is not as easy as it may seem.
We're here to assist all employers and hiring managers who choose to recruit professional Kotlin developers on their own. Hiring a developer on your own requires a fair amount of software development experience in general. However, if you're a non-technical manager interested in learning more about the hiring process of a Kotlin developer, we've put up an excellent resource for you.
Skills to look for in a Kotlin developer?
1. Solid expertise in Kotlin along with other programming languages
Extensive knowledge of Kotlin along with similar programming languages like Java, Scala, Python, Groovy, etc., is a necessary skill for professional Kotlin developers. A skilled developer is expected to have advanced knowledge of the languages’ syntax and structure. In addition, you should consider a candidate with a good understanding of object-oriented fundamentals (e.g. inheritance, class, and static methods), variables, lists, loops, as well as the ability to apply these concepts in different parts of the language.
2. Experience in vital Android SDK concepts
One of the most important traits of being a Kotlin developer is leveraging the Android Software Development Kit (Android SDK). It is used by developers to create and develop software and applications for different online platforms including, documentation, libraries, coding samples, etc., and provides guidance to application developers in creating software by integrating these codes and documentations.
3. Good knowledge of the entire software development life cycle (SDLC)
The software development life cycle is a framework for developing applications that follow technological needs and consumer requirements. It consists of several stages and establishes an international standard that developers can use to enhance and create their programs.
Using the well-defined development framework, Kotlin developers can create high-quality software on time and within budget. It is essential to look for a candidate who is well-versed in the language to perform various application features like wireframing the app's screens, software planning, user interface (UI) design, coding and integrations, testing, and submission to the App Store.
4. Proficiency with Android studio
The knowledge of an Integrated Development Environment (IDE) such as Android Studio or any other platform is an important skill to have. This would aid in working more efficiently and offer benefits such as the built-in debugger and other testing tools to write bug-free code. As a result, Kotlin developers are required to have a good understanding of the environment to produce best-in-class mobile solutions.

5. Proficient database/SQL skills
Almost every application needs to store data in a particular way. This could either be the app or user data, consequently, the app should be integrated with a database to ensure proper data management. With this, several employers are looking to hire Kotlin developers withSQL or other database experience.
6. Understanding the business knowledge of an Industry
It is critical for Kotlin developers to have the business knowledge of a certain industry. They typically build mobile apps for various industries like healthcare, entertainment, real estate, etc. Look for a candidate with a decent understanding and relevant working experience to successfully navigate the industry. A developer who has a deep knowledge of the user’s needs and which Android app features could be most useful for the target audience can build a more effective application and yield higher profits for the business.
7. Ability to collaborate effectively with other team members
It is extremely important for all software engineers and Kotlin developers, in particular, to build and maintain effective communication with other members of the team like the UI/UX designers, back-end developers, product managers, etc. Since every member of the team performs a specific role in most companies, excellent communication is key to building outstanding products.
