Essential Skills to Look for When Hiring React Native Developers
Developers should be comfortable with libraries like React Navigation or linking native code to React Native components. When you hire React Native developers, ensure they possess deep knowledge of developer tools such as React DevTools for debugging and optimization.
To get hired as a React Native developer, engineers need a strong foundation in JavaScript, React, and mobile development. Building a portfolio of projects and actively participating in the React Native community can also help them stand out.
Proficiency in JavaScript and React
A strong foundation in JavaScript and React is crucial because React Native application development relies heavily on these technologies. Without expertise in core JavaScript concepts like closures, async/await, and promises, or React’s component lifecycle and hooks, developers will struggle with complex applications.
- Coding Test: Present a task requiring both JavaScript and React fundamentals. For example, ask the candidate to create a reusable component that interacts with an API using async/await.
- Ask Questions: Ask the candidate to explain how they handle state management in React, or how they would optimize React components to reduce re-renders.
- “How do you handle performance issues caused by excessive re-renders in React applications?”
- “Can you explain the difference between promises and async/await in JavaScript, and when you’d use one over the other?”
Native Mobile Development Experience
Developers who understand native mobile development for iOS or Android will have a deeper understanding of platform-specific requirements, leading to more optimized React Native apps. This background also helps when bridging gaps between React Native and native code.
Consider candidates who have experience integrating React Native with web applications to create seamless transitions between native mobile apps and web app functionality.
- Portfolio Review: Ask to see any native applications they’ve built or contributed to.
- Practical Exercise: Ask the candidate to solve a problem where they need to integrate a native iOS or Android feature into a React Native app.
- “Can you describe a situation where you had to integrate a native feature into a React Native project? How did you handle the differences between iOS and Android?”
React Native Framework
A strong understanding of the React Native framework, including its architecture and APIs, is crucial for efficient app development. Candidates should be comfortable with libraries like React Navigation or linking native code to React Native components.
- Technical Discussion: Ask the candidate to describe how they structure React Native projects and handle challenges like navigation or state management.
- Coding Test: Challenge them to solve a problem involving the creation of a new feature using the core React Native API.
- “How would you manage navigation between multiple screens in a React Native app? What library would you use and why?”
- “Can you walk me through how you’d set up deep linking in a React Native application?”
Mobile UI/UX Design
Knowledge of UI/UX design principles is crucial for delivering intuitive and visually appealing mobile apps. React Native developers need to understand how to implement responsive, interactive designs that provide a consistent user experience across devices.
- Design Task: Provide a design mockup and ask the candidate how they’d implement it in React Native, focusing on mobile UI/UX principles like responsiveness and accessibility.
- Portfolio: Review examples of apps the candidate has worked on and assess the user experience.
- “How do you ensure that the user interface looks good on both small and large screens?”
- “Can you describe a time when you implemented a challenging UI in React Native? How did you ensure a good user experience?”

Cross-Platform Development
React Native’s ability to develop for both iOS and Android makes it critical for developers to understand how to build and deploy apps for multiple platforms while managing differences between the two.
- Scenario-Based Question: Ask about how they handle platform-specific code (e.g., using the Platform module in React Native).
- Practical Task: Give a cross-platform challenge, such as creating a feature with different behavior on iOS and Android.
- “How do you manage platform-specific requirements in a cross-platform React Native project?”
- “Have you ever encountered a scenario where something worked on Android but not on iOS (or vice versa)? How did you resolve it?”
State Management
Managing app state is essential for React Native development. Candidates should be proficient in state management tools like Redux, Context API, or MobX to handle complex app data.
- Code Challenge: Ask the candidate to implement state management for a specific scenario (e.g., managing form state or syncing state across components).
- Discussion: Ask how they approach state management in React Native apps, especially when scaling.
- “Can you explain the difference between Redux and Context API, and when you would choose one over the other?”
- “How do you handle global state in a React Native project with complex data flows?”
Testing and Debugging
Writing testable and debuggable code is crucial for maintaining high code quality. Candidates should know how to use frameworks like Jest for unit testing and be familiar with debugging tools like React Native Debugger.
- Testing Challenge: Ask the candidate to write unit tests for a small React Native component or function using Jest.
- Debugging Task: Present a React Native bug and ask the candidate to debug it using React Native tools.
- “What testing strategies do you use to ensure the reliability of your React Native code?”
- “Can you walk me through your debugging process when dealing with an unresponsive component?”
Performance Optimization
Optimizing React Native apps for performance is key to ensuring a smooth user experience on both native mobile apps and mobile devices. Developers should know how to reduce bundle size, optimize image loading, and manage rendering efficiency.
- Optimization Task: Ask the candidate to optimize a simple React Native app for performance, focusing on reducing load times and improving rendering speed.
- Code Review: Ask them to walk through their approach to performance optimization for a past project.
- “What techniques do you use to optimize performance in React Native apps?”
- “Can you give an example of how you improved the performance of an app? What tools or strategies did you use?”
