Take turns: One student acts as interviewer while the other answers using the STAR technique (Situation, Task, Action, Result).

Q1React Native Core Architecture

How does the React Native New Architecture (Fabric & TurboModules) improve communication over the legacy JS bridge?

STAR Answer Strategy Tip:

Discuss JSI (JavaScript Interface), synchronous C++ bindings, eliminating asynchronous JSON serialization bottlenecks.

Q2Mobile Systems Architecture

How do you architect an offline-first mobile application with background synchronization?

STAR Answer Strategy Tip:

Cover local SQLite/WatermelonDB storage, optimistic UI updates, conflict resolution strategies (e.g. last-write-wins).

Q3Mobile Rendering Performance

Walk through optimizing 60 FPS list scrolling in React Native when rendering hundreds of media items.

STAR Answer Strategy Tip:

Mention FlashList, recycling views, getItemLayout to bypass measurements, memoizing renderItem, and resizing images.

Q4Native Platform Invariants

What are the key differences in permission handling between Android 13+ (Runtime) and iOS?

STAR Answer Strategy Tip:

Explain explicit runtime permission prompts, graceful degradation when users deny permissions, and OS privacy policies.

Q5Engineering Tradeoffs

Why does cross-platform React Native fit early-career startups better than separate Swift and Kotlin codebases?

STAR Answer Strategy Tip:

Highlight unified team velocity, shared TypeScript business logic with web, and single bug-fix deployment via OTA updates.
