React Test
The React Test is an intermediate screening assessment for hiring teams who need to check practical React knowledge before interviews. It helps identify candidates who understand components, props, state, effects and rendering behaviour in everyday front-end work.
Summary of the React Test
The React Test is an intermediate screening assessment for hiring teams who need to check practical React knowledge before interviews. It helps identify candidates who understand components, props, state, effects and rendering behaviour in everyday front-end work.
3 dimensions, scored separately
Components & props
This measures whether a candidate understands how React components receive and use data through props. It matters because most production React work depends on building reusable components with clear, predictable inputs.
State & effects
This measures how well a candidate understands state updates, effect usage and common mistakes in component logic. It matters because poor handling of state and effects leads to bugs, confusing behaviour and hard-to-maintain code.
Rendering behaviour
This measures whether a candidate can reason about what causes renders and how React applies updates. It matters because developers need to predict render outcomes to debug issues and avoid inefficient or incorrect UI behaviour.
Everything about the React Test
Pair this test with the rest of the first round: springhire's candidate screening software adds a one-way video interview and resume scoring to the same candidate link, ranked in one report.
01What is the React Test?
This React Test measures whether candidates understand the core ideas needed to work effectively in a React codebase. It focuses on components and props, state and effects, and rendering behaviour, using scenario-based multiple choice questions that reflect common development decisions. Candidates are asked to reason about how data flows through components, how state updates behave, and what happens during render. The question set is drawn from a larger bank, so each candidate sees a varied mix. On Springhire, this gives hiring teams a quick way to compare applicants on the React concepts that matter in day-to-day front-end work.
02How does the React Test work?
This is an intermediate knowledge test with 20 auto-scored multiple choice questions, completed in 10 minutes. Questions are drawn from a 60-question bank and randomised per candidate, which helps reduce answer sharing while keeping the assessment consistent across applicants.
03Why is the React Test important to employers?
React candidates often sound confident in interviews but struggle with basic patterns once they start work. This test reduces the risk of moving forward with applicants who can repeat terms like props, state or effects without understanding how React actually behaves when code runs in a real component tree.
How to interpret React Test results
Every candidate report scores each dimension separately. Here is what high and lower scores typically look like at work, and how to use them in your hiring decision.
Components & props
High scorers: A high score suggests the candidate can work confidently with component inputs and structure reusable React UI in a clear way.
Lower scorers: A low score suggests the candidate may confuse how props are passed, read or used inside components.
State & effects
High scorers: A high score suggests the candidate understands state update patterns and can use effects without creating avoidable bugs.
Lower scorers: A low score suggests the candidate may struggle with asynchronous updates, effect dependencies or common state handling mistakes.
Rendering behaviour
High scorers: A high score suggests the candidate can predict how React re-renders components and reason through UI update behaviour.
Lower scorers: A low score suggests the candidate may have trouble explaining why components render or how repeated updates are applied.

Build a multi-measure assessment: tests to pair with the React Test
Next.js Test
The Next.js Test helps hiring teams assess intermediate frontend candidates on practical framework knowledge. It is suited for roles that build or maintain modern web apps and need sound judgment on routing, rendering choices and data fetching.
View testGraphQL Test
The GraphQL Test is an intermediate screening assessment for developers who work with APIs and modern web apps. It helps hiring teams check practical knowledge of schema design, queries and mutations, and performance issues such as N+1 problems and caching.
View testDjango Test
The Django Test is an intermediate screening assessment for hiring teams that need to evaluate practical Django knowledge quickly. It helps identify candidates who understand common framework patterns in models, views, templates, and built-in security basics before moving to interviews.
View testFastAPI Test
The FastAPI Test is an intermediate screening for hiring teams assessing developers who will build or maintain Python APIs. It checks practical knowledge of routing and typing, request validation, and core async concepts, helping you identify candidates who can work safely and clearly in FastAPI.

Frequently asked questions
It measures intermediate React knowledge in three areas: components and props, state and effects, and rendering behaviour. The questions focus on how candidates reason through common React scenarios, not on memorising obscure syntax.
This test fits candidates for front-end roles that use React regularly, such as Front-End Developer, React Developer or UI Developer. It is best used when React knowledge is a real requirement of the job.
Start with the overall score to see whether the candidate meets the level you need, then review the skill breakdown. Strong dimension scores suggest reliable understanding in that area, while weaker scores show where follow-up interview questions are needed.
It is designed at an intermediate level, so it works best for candidates expected to be productive in an existing React codebase. For junior hiring, use it as a learning signal rather than a strict cutoff, and for senior hiring, pair it with deeper technical interviews.
The test uses multiple choice questions based on realistic React situations, such as how a child component should use a prop or what to check when repeated state updates do not behave as expected. This helps you assess practical understanding that carries into day-to-day work.
