Node.JS Developer Test

Use a Node.js test to hire developers by testing their knowledge and understanding of Node.js.

  • What is a Node js test?

    The Node.js test is used to assess programmers and developers on their ability to use the open-source server environment, and their knowledge of the structure and architecture.

    This type of test is designed to see how competent an applicant is, and is typically used early in the recruitment process to provide quantifiable data regarding the skills of the candidates, so that only the most qualified are taken further in the hiring process.

    The assessment tests candidates' knowledge of setting up and executing Node.js code, using related tools and packages, as well as working with developing and producing Node.js APIs.

Identify the best candidates and hire faster

Our pre-employment tests let you drill down to the best candidates at the click of a button.

  • Find those candidates who will excel in the role.

    Select the assessments that match the skills or behaviours for the position. You can test for software or coding competency, soft skills like teamwork, or personality traits, to be sure those who pass have high potential.

  • Reduce costs and time.

    No more laborious sifting of resumes or cover letters. Pick your ideal assessment mix, invite your applicants to take them, see the results in your dashboard. Get to the interview stage fast.

  • Eliminate bias.

    All your candidates take the assessments on a level playing field. Only their results determine whether they get shortlisted.

  • Why is a Node js test so important when hiring?

    The Node.js pre-employment screening test is an important part of the recruitment process for any role that needs Node.js knowledge, because it is a real-time snapshot of the developer's abilities, providing data that is hard to get in any other way.

    When a popular programming or coding role is advertised, recruiters can be faced with potentially hundreds of similarly qualified candidates - and getting an idea of the breadth of their Node.js knowledge and experience from a CV is not easy. It is also not easy to assess through interviews, either.

    The Node.js test takes candidates through the architecture of Node.js, allowing them to demonstrate their knowledge of this single-threaded programming structure, and shows their knowledge of design patterns and their architectural vision.

    With the results of the assessment, the recruitment team can easily narrow down a large applicant pool to a smaller number, ready for the next stage in the process. Using the Node.js test as part of the recruitment process saves time and money, but also reduces the risk of a bad hire with quantifiable data.

    The Node.js assessment is designed to be used when recruiting Node.js developers, or for software engineers that need to be comfortable generating dynamic page content, collecting, adding, deleting and modifying data, and working with files on the server using asynchronous programming.

Sample Node.JS Developer Test question

Which of the following statements about $push and $addToSet is incorrect?

  • $addToSet adds an element to an array only if this element doesn't already exist in the array.

  • Their behavior is exactly the same.

  • Both add elements to array fields in Mongoose.

  • $push adds an element to the end of an array.

How to assess Node js coding skills using our test

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

The Node.js 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 Node.js 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.

Node.JS Developer Test FAQs

What is a Node.js specialist?

A Node.js specialist is a software or programming developer that has specialist knowledge and experience working with Javascript in the open-source server environment. A Node.js specialist has extensive skills in creating, developing, and working with APIs as well as using Node.js to create single-threaded programming.

Is the Node.js test difficult?

As with other pre-employment assessments, most of the difficulty of the Node.js test comes from the unfamiliarity with the structure and layout, and the test pressure including a time limit. For someone who is confident in the use of Node.js, the content of the assessment should not be too challenging.

What other skills are required for Node.js?

Node.js specialists and developers usually need to be proficient in using JavaScript and aware of different developing environments, both front end and back end. Node.js requires logical thinking to program, and the ability to see the wider business picture for the best designs.

Why is knowledge of Node.js important?

Node.js is a popular piece of open-source software, and it is widely used in many different tech roles. It is also quite a particular piece of engineering that needs specialist knowledge to operate, and this knowledge should be tested before a developer is hired to be sure that the candidate has what it takes to be successful.
