About the Kotlin ~ Advanced Test
The Kotlin Advanced Test is designed to evaluate a developer’s expertise in advanced Kotlin programming, ensuring proficiency in writing efficient, scalable, and maintainable applications. This test covers core Kotlin features and advanced techniques used in modern software development, making it ideal for experienced Kotlin developers, Android developers, and backend engineers working with Kotlin-based applications.
Key topics include object-oriented and functional programming, where candidates are assessed on data classes, sealed classes, extension functions, and higher-order functions. Mastery of immutability, lambda expressions, and inline functions is essential for writing concise and efficient Kotlin code.
The test also evaluates concurrency and coroutines, focusing on structured concurrency, coroutine scopes, dispatchers, and asynchronous programming techniques for handling background tasks efficiently. Candidates must understand exception handling and resource management to ensure robust error handling in applications.
Another critical area is Kotlin’s collections framework, assessing knowledge of immutable and mutable collections, sequence operations, and transformations. Understanding delegation and property delegation is also crucial for optimizing code structure and reusability.
Additionally, the test covers metaprogramming and DSLs, evaluating candidates' ability to create expressive and flexible APIs. It also assesses expertise in mobile and backend development, testing the use of Kotlin for building modern applications with structured architecture, state management, and efficient data handling.
