DevSkiller JavaScript coding questions are powered by the RealLifeTesting™ methodology, which is uniquely designed to allow recruiters to send applicants a JavaScript test that aims to mirror the real challenges they will face when working for your business. Meaning you can accurately test exactly how well each applicant will perform on the job, during the screening process. This method allows you to accurately assess a JavaScript developer’s time-management skills, problem-solving ability, and JavaScript coding skills- all before the interview stage.
Skills covered in our JavaScript coding questions
JavaScript (or JS) is a multi-paradigm programming language that is one of the most popular programming languages in use today. Due to its popularity, it can be hard to narrow down the right JavaScript developer. Here’s what to look out for:
The basics of JavaScript are relatively easy to pick up meaning a lot of developers only learn what they need to get things done. However, a good JavaScript developer will need to have good background knowledge of the language itself in order to be able to write high-quality applications.
JavaScript also develops very quickly and new frameworks are created each day, meaning it is a positive, if even a Junior JavaScript developer, can demonstrate a good knowledge of popular frameworks. However, it is perhaps more important to have a JavaScript developer who can demonstrate knowledge of older JavaScript frameworks or libraries and therefore a deeper understanding of the language as a whole.
It is also important to understand that a JavaScript developer will have a different knowledge base depending on their experience and the role they are applying for. For instance, a front-end developer will require a different skill set to a full stack developer. In these cases, core knowledge of the language will be the same, but each developer should also have specific knowledge related to their field of work.
If you are hiring for a higher level position then commercial experience will also be required, but for a mid-level or junior JavaScript developer, a portfolio containing some well-written code will suffice.
DevSkiller JavaScript coding questions are completely adaptable so they can be customized to suit your company’s requirements. You can choose the programming language being assessed, the time each test will take to complete, and even monitor the tests in real-time.
Knowing how best to invest your company’s money can be a daunting prospect, so don’t take our word for it, here is what our clients have to say:-
Spartez is a Platinum Top Vendor on the Atlassian Marketplace. The company focuses on the Atlassian and agile ecosystem, providing useful tools for Server and Cloud, as well as offering support to customers and evaluators.
Before turning to DevSkiller, Talent acquisition specialist at Spartez- Patrycja Kiljańska and her team, used to screen interview candidates using an in-house solution which resulted in more than 23% of candidates passing the initial test. This made it incredibly difficult to decide who to bring back for the next phase, which then led to recruiters conducting far more interviews than were necessary. Furthermore, screening each test took around 15-20 minutes to evaluate, adding to the strain of their workforce. The result was that the whole process was inefficient and labored.
DevSkiller’s testing is evaluated automatically and after turning to DevSkiller to conduct a more thorough screening process for candidates, Spartez found that only 10.23% of applicants made it past the first stage of technical screening and that the company as a whole, were able to filter down 43% more candidates during the recruitment process, before arranging a one-to-one meeting.
“We’ve replaced a high-maintenance in-house solution with DevSkiller. Our process looks the same, however, the product gives us better performance. The results are also way easier to assess.”
The RealLifeTestingTM methodology is the foundation of all DevSkiller JavaScript coding questions. The program is designed to simulate real, everyday JavaScript scenarios that your developer applicants are likely to encounter in their work. This method of testing allows recruiters to have a comprehensive understanding of an applicant’s skill level from the very beginning of the screening process.
Only the candidates most adept at the role, are able to demonstrate the clear understanding and knowledge required to progress through the JavaScript test.
Setting up Java coding questions takes no time at all and can be ready to send in as little as 5 minutes. DevSkiller stores an extensive library of coding tests and JavaScript questions, meaning you can start assessing JavaScript developer candidates as soon as you set up your account.
The great thing about DevSkiller is it has been designed to generate results automatically and runs with as little external input as possible. This means that ready-to-use tests can be carried out by recruiters who have little knowledge of programming themselves and then results are presented in a simple, easy to understand manner. Furthermore, if you do have someone who is technically minded carrying out the recruitment process, then the tests can even be prepared from scratch.
The advantage the DevSkiller model has is that Java coding questions can be assessed automatically. This means that the DevSkiller model can also implement stringent anti-plagiarism tools to ensure each test’s authenticity. For instance, checks can be carried out to see if the candidate is looking at a different screen while carrying out their test. DevSkiller can also automatically cross-reference each candidate’s coding and answers, with answers given by previous candidates and if there is a match the system can categorically filter out any cheating.
Developer candidates are overwhelmingly positive in their feedback of the DevSkiller model of using JavaScript tests. The vast majority of developers enjoy the opportunity to be able to demonstrate their technical skills in a way that is relevant to their work. Most also appreciate that DevSkiller tests use coding tools and conventions like unit testing, and cloning to GIT from a personal IDE.
Many developers can be suspicious of academic algorithmic tests and some even refuse to take them at all, as these don’t test the skills that developers actually use day to day and might ask for knowledge of something they haven’t used practically in years. With DevSkiller tests however, developers notice the difference and appreciate being able to demonstrate their technical skills.
