Screening questions go out by email right after a candidate enters the pipeline. Answers are scored against the skill matrix, with a written reason. Here are three from the React Native library.

1. Q1 What is different between iOS and Android in a React Native app you shipped?
2. Q2 A long list stutters on older Android phones. What do you check?
3. Q3 When did you need native code, and how did you add it?

What does the React Native coding task look like?

Chat inbox screen. Build an inbox list that loads threads, paginates smoothly, shows unread counts and works offline. Time limit 75 minutes.

1. Render a virtualized list with pagination
2. Cache threads for offline use
3. Handle pull to refresh and errors
4. Test the data hook logic

export function Inbox() {
  const { threads, loadMore, refresh, offline } = useThreads()
  return <FlatList data={threads} keyExtractor={t => t.id} onEndReached={loadMore}
    refreshing={false} onRefresh={refresh} ListHeaderComponent={offline ? <OfflineBanner /> : null}
    renderItem={({ item }) => <ThreadRow thread={item} />} />
}

How much does a React Native developer cost?

Pay varies a lot by country, city, seniority and company. Public salary surveys show broad yearly ranges like these for mid-level to senior React Native developers. Treat them as a starting point and check current surveys for your market.

React Native engineers who can also write native modules usually earn more than those who stay in JavaScript only.
