What is a React test?

A React test assesses how well candidates can use React, an open-source library for building user interfaces. It gives insight into the level of skill a front-end developer has to create complex and engaging web applications.

Assessing React proficiency helps to ensure the strongest candidate for the role, with the necessary grasp of React and its functionality, is selected in the recruitment process.

The test evaluates the ability to create advanced hooks, use state management of class and functional components, create design patterns, and realise a few other advanced concepts.

Candidates will need to display competency across these skills if they are to progress to the next stage in the hiring process.

About the React Test

React is a highly popular JavaScript library. First released by Facebook in 2013, React is commonly used because it makes the creation of dynamic applications much simpler.

React is used for web application UI, whilst the React Native framework facilitates cross-platform mobile application development on iOS, Android, and Windows.

React provides both speed and stability, allowing high-load applications to function optimally. These features have secured its widespread use, so assessing React development skills as part of the recruitment process is prudent.

Why should you use a React test for recruiting?

Using a React test as part of your recruitment process is a quick and easy way to determine whether prospective employees have the level of React experience required for your vacancy.

Skills such as React are commonly listed on developers’ resumes, but the insight that can be gained from reviewing a candidate’s experience on paper is limited. A React test can be used to substantiate claims made, confirming the level of skill possessed.

A React skills test can be administered in combination with other coding and software skills tests, to gain a full picture of a prospective employee’s technical talents.

These skills tests are effective when administered as screening tools after application form submission, or when used as part of an assessment centre.

Job roles for which a React test may be a useful prerequisite include:

  • Front-end Developer
  • Full-Stack Developer
  • React Developer
  • UI Manager

Targeted skills testing, such as using a React test, allows for objective streamlining of the talent pool based upon assessment data. This ensures that the strongest candidates advance in the process and avoids any unintended bias.

Thanks to skills tests, quicker and more effective hiring decisions can be made – saving time and money and increasing productivity and profit.

How our test assesses React skills

In Neuroworx’s React test, candidates will need to answer a range of questions targeting an intermediate level of proficiency, from demonstrating knowledge about the framework to understanding how to create advanced hooks, use state management of class and functional components, and create design patterns.

The test is designed to indicate how well a candidate understands React based on a final test score, which can then be compared to the scores of other applicants.

The multiple-choice questions consist of one correct answer and two to four distractors. The distractors are mostly generic mistakes or misconceptions, which makes the test challenging and helps measure a candidate’s proficiency more accurately.

During the development process, the test was rigorously analysed to maximise reliability and validity in line with industry best practices. It was created and reviewed by programmers and psychometric experts, and field-tested with a representative sample of job applicants who have varying React experience, just like you might find in a talent pool.

Each test is reviewed by a panel of individuals representing diverse backgrounds to check for any sensitivity, fairness, face validity and accessibility issues. This ensures each programmer has a fair chance of demonstrating their true level of React proficiency and feels the test is of high quality.

Our programming tests are monitored to ensure they are up-to-date and optimised for performance.

Frequently asked questions

What are the advantages of React?

React is used for its speed and stability, as it can support the performance of high-load applications. It effectively uses a virtual DOM (Document Object Model) for rapid rendering of dynamics.

The library also allows for the reuse of system components, increasing consistency and aiding the maintenance of the code. React components can be written in JSX or JavaScript.

How popular is React?

Facebook and Instagram continue to use React for their platforms, as do many other Fortune 500 companies (Airbnb and Tesla, for example). The BBC’s website and streaming platform is also built using React.js.
