React Developer Test

Use a React developer test to hire developers by testing their knowledge and understanding of React.

  • What is a React test?

    React is a front-end Javascript library used by developers to build user interfaces (UI's). Used when building web applications, React enables developers to build dynamic buttons, search bars, or facilities on a website that enable a user to interact directly with the website.

    A React test allows recruiters to determine how well candidates can use the React library to create the most commonly used user interfaces on websites. Also, it helps demonstrate how well the candidate can use React programming to solve common and complex problems.

  • Why is a React test so important when hiring?

    React is a commonly used Javascript library used by many developers. As such, many developers must be familiar with and proficient in using React when developing websites.

    Practically and objectively assessing a candidate's skill level in using React can be tricky for recruiters, especially when candidates state the same proficiency level. The React test provides recruiters with an easy-to-administer way of assessing how well candidates understand React and whether they demonstrate the necessary skill level and knowledge to use React in a role.

    Those who score highly on a React test show the skill level required and can progress to the next stage of the application process. Those that do not can be eliminated.

    In addition to evaluating a candidate's proficiency in using React, the React test also enables recruiters to understand better how well candidates can work under pressure along with their ability to problem-solve.

    An individual's critical thinking and analytical skills are also assessed in this test, providing you with an opportunity to evaluate many of the skills required by those that use React daily in their roles.

    Using a React test in the recruitment process for many related positions would provide beneficial insights into the skill level of your applicant pool.

    Examples of such roles include:

    • JavaScript developer
    • Front-end web developer

How to assess React coding skills using our test

Our React test asks a variety of questions that vary in difficulty level. Candidates who are proficient in React should be able to answer most of the questions correctly.

The React test provides valuable data-driven insight into what a candidate knows and understands. The test is structured using multiple-choice questions: a familiar format for most test-takers, that allows for instant and objective scoring.

As well as the correct answer, there are typically 2–4 distractors, representing common misconceptions and mistakes. This helps make the test more challenging, so a candidate's ability can be measured more accurately.

Test scores are provided to the user and can be compared to other test-takers in your talent pool to see how they perform relative to each other.

Each test has been thoroughly reviewed to ensure accuracy and validity in line with industry standards. It has been written, examined and edited by React experts and psychometric professionals. It has also been reviewed by a diverse sample of job seekers to check for any issues including sensitivity, face validity, fairness and accessibility.

This test is continually monitored so our team can optimize performance and regularly assess fairness issues.
