Hire React developers by skill

Which screening questions work for React roles?

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 library.

1. Q1 Walk us through a form you built in React. How did you handle validation and errors?
2. Q2 When do you reach for a global state library, and when is it overkill?
3. Q3 A list of 5,000 rows feels slow. What would you measure and change?

What does the React coding task look like?

Searchable team directory. Build a directory screen that loads people from an API, filters by name and team, and works with a keyboard. Time limit 75 minutes.

1. Fetch data with loading and error states
2. Add a debounced search and a team filter
3. Make rows keyboard and screen reader friendly
4. Write tests that type into the search box like a user

export function Directory() {
  const [query, setQuery] = useState('')
  const { data, error, isLoading } = usePeople(useDebounce(query, 250))
  if (error) return <ErrorState retry />
  return <PeopleList people={data ?? []} busy={isLoading} />
}

How much does a React 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 developers. Treat them as a starting point and check current surveys for your market.

React engineers who also own design systems or deep performance work tend to earn more than those focused on feature screens.
