Pre-Screening Video Interview Questions for React Native Developer

These questions are ideal for one-way video interviews on ScreeningHive. They are designed to quickly evaluate technical knowledge, communication skills, and problem solving before scheduling live interviews.

1. Briefly describe a recent React Native project you worked on and your specific responsibilities.

   This evaluates practical experience, role fit, and ability to summarize contributions concisely.

2. How do you decide between using a managed workflow like Expo and ejecting to a bare React Native project?

   This evaluates decision making around tooling, trade offs, and platform requirements.

3. Explain how you would improve the performance of an app that is slow to launch and has janky animations.

   This assesses problem solving, profiling knowledge, and practical optimization techniques.

4. Describe your approach to handling app state, including an example of a complex state flow you implemented.

   This measures understanding of state management patterns and clarity in explaining architecture.

5. How do you ensure your mobile app is accessible and provides a good user experience across devices?

   This checks awareness of accessibility best practices, testing strategies, and UI consistency.
