React Native interview prep
Senior React Native interviews test the boundary: what happens between JavaScript and native, where performance goes, and when you would write a native module instead of another dependency.
What the React Native loop scores
| Round | What the interviewer writes down |
|---|---|
| JavaScript and React | Rendering, memoisation and effects, explained from a real screen. |
| The native boundary | The new architecture (JSI, Fabric, TurboModules) and what it changed in practice. |
| Performance | Lists, images, animations and how you measured the problem. |
| State and data | Where the source of truth lives and how offline behaves. |
Loops differ by company. This is the common shape of senior loops, not a promise about any one employer.
The second question
Follow-ups that decide the round
“The list drops frames on Android only. Where do you start?”
Tests whether you can separate a JavaScript problem from a native one.
“Would you write this as a native module? Why?”
Tests judgement about the boundary, not loyalty to a framework.

There is no interactive React Native practice yet, and this site will not pretend there is. The question bank is the honest starting point; the guides show how answers are scored.
