Node.js tests are designed to assess a candidate's understanding and ability to use the Node.js platform.
Node.js is a JavaScript runtime environment that is open-source, cross-platform, and is used in back-end development to execute JavaScript code outside a web browser.
The Node.js test is a simple assessment of the skills needed to confidently use all the functionality of the Node.js system, from modules to packages, and create dynamic web pages.
Used by many well-known businesses like GoDaddy, LinkedIn, PayPal and Netflix, Node.js allows developers to use event-driven architecture and asynchronous programming to optimise both throughput and scalability in databases and servers.
For businesses who want to hire Node.js developers, the right test of skills, knowledge and experience is needed to ensure that the candidates are qualified to perform the role.
The Node.js test assesses the capabilities of the candidate in understanding the platform and architecture of the environment, as well as the various modules and packages.
The assessment also ensures that the applicant understands how to take advantage of asynchronous (single-thread) I/O, how to interface with different runtime environments, and how to scale using cluster or pm2.
It also assesses the candidate on their skill in making add-ons using N-API, navigating the npm (pre-installed package manager), and using web frameworks developed by the open-source community.
Employing a new developer can be difficult when so many will have listed that they are competent or confident in Node.js on their resume. Some of the common roles that would require Node.js knowledge and experience include:
Node.js Developer
Back-End Developer
Getting past the paper sift portion, especially for a popular role, can still leave the recruitment team with an unwieldy talent pool. This is where using a Node.js test as pre-employment screening can make a real difference.
HR and recruitment teams are skilled at hiring, but they may not have the technical or programming knowledge to recognise the right skills, knowledge and experience in JavaScript and runtime environments to be able to recognise a good candidate. So a non-biased, simple assessment created by an expert should be used to whittle down potential candidates and decide who to take forward to the next stage of the recruitment process.
The Node.js assessment can be completed by the candidate in their own time. Once the test is completed, an easy-to-read report is produced that can inform the recruitment team about the candidate’s ability with Node.js and whether they have the required level of skills and knowledge.
Written by a Node.js expert, the Node.js assessment is the simple solution to learning what skills the applicants for your job role possess and how easily they can navigate both JavaScript and the ever-growing list of useful modules and packages.
Which of the following allows us to check the current NPM version?

Results for the Node.js Test along with other assessments the candidate takes will be compiled to produce a candidate report.
The report is automatically generated and available both online and as a downloadable pdf so they can be shared with other team members and employees alike.
In Neuroworx’s Node.js test, candidates will need to answer a range of questions targeting an intermediate level of proficiency, from demonstrating their understanding of the Node.js platform and architecture to their skills in making add-ons using N-API. The test is designed to indicate how well a candidate understands Node.js 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 Node.js 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 Node.js 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.

Testimonials
Provides all the data and high-level metrics we need to make fast hiring decisions. Neuroworx has been particularly helpful in scaling our operations since we moved to remote working.
Focusing on data reduced the subjective decision making from our hiring process and allowed us to reduce bias and make better hiring decisions.
We used Neuroworx as part of our Finance Graduate Scheme recruitment and it was just what we needed – really simple to send candidates the link to complete and clear to see how they all compared. And great value for money!
Origins
Node.js is used for server-side scripting to create dynamic web pages. It is also used to create both server-side and client-side scripts on a single programming language, with an event-driven architecture that allows input and output processing to continue before processing has finished, making it simple and easy to use.
JavaScript is still the most popular programming language, and Node.js is the only runtime environment that translates this typically front-end language into server-side scripting for dynamic web pages.
The common belief is that to be an effective full-stack developer, candidates need to have knowledge of MongoDB, Express.js and Node.js (known as the MEAN stack). However, in most cases, Node.js is the only tool that can’t be replaced with other software that has similar functionality.
