Gradle
Gradle is a popular tool that helps developers build and manage mobile apps, especially Android applications. Think of it as a recipe book and kitchen manager combined - it handles all the complex steps needed to turn the developer's code into a working app. It automates repetitive tasks, manages external tools and libraries the app needs, and ensures everything works together smoothly. While similar tools like Maven or Ant exist, Gradle has become the standard choice for Android development because it's more flexible and easier to use. When you see Gradle mentioned in a resume, it usually indicates the person has experience with professional Android app development.

Example Interview Questions
Senior Level Questions
Q: How would you optimize build times in a large Android project?
Expected Answer: A strong answer should mention practical solutions like using Gradle's build cache, parallel execution, incremental builds, and organizing multi-module projects efficiently. They should also discuss monitoring and measuring build performance.
Q: Explain how you would set up different build variants for an Android app?
Expected Answer: The candidate should explain how to create different versions of an app (like free/paid or development/production) using Gradle configurations, and how to manage different features and resources for each version.
Mid Level Questions
Q: How do you manage external libraries in a Gradle project?
Expected Answer: Should explain how to add and update external libraries, handle version conflicts, and organize dependencies in a maintainable way. Should mention the difference between different dependency types.
Q: What's your approach to creating custom Gradle tasks?
Expected Answer: Should be able to explain how to create basic automation tasks for common development needs, like copying files, running tests, or generating reports.
Junior Level Questions
Q: What is Gradle and why is it used in Android development?
Expected Answer: Should be able to explain that Gradle is a build tool that helps compile the app, manage libraries, and automate common tasks. Should understand basic Gradle file structure in Android projects.
Q: How do you add a new library to an Android project using Gradle?
Expected Answer: Should be able to explain how to add simple dependencies to the build.gradle file and understand basic dependency syntax.
