When hiring a JavaScript Developer, look for demonstrable skills in JavaScript and relevant frameworks like React, Node.js, or Angular. They should be proficient in writing and checking code, adhering to development standards, and maintaining code without needing extensive rewrites.

The ideal candidate will be able to diagnose and fix issues in both front-end and back-end environments and ensure smooth transitions from test to production. You can assess their capabilities in key areas such as JavaScript debugging, algorithms, data structures, and frameworks like React Native, Ionic with React, and Vue.js using tools like TestGorilla.

Individual tests can range from 15 to 45 minutes, depending on the tests you choose. We generally recommend using our universal coding test, alongside tests for soft skills and custom questions to get the best measure of a developers' skills.

Our JavaScript coding tests are designed to assess relevant skills based on the specific role you're hiring for. The tests and challenges therein are designed by experts to reflect real-world coding challenges, ensuring fairness in evaluating candidates at various experience levels.

We also provide a variety of anti-cheating monitors including coding timelines, to ensure full visibility over the candidates' attempt across the duration of the assessment.

As part of a skills-based hiring process, we recommend taking your shortlisted applicants through a structured interview process. This means asking a pre-defined set of questions to all of your candidates with the intention of getting a well-rounded picture of their skills and capabilities.

• What are the different data types in JavaScript?

• Explain the purpose of callback functions in JavaScript.

For advanced JavaScript developers, you can use more complex questions like:

• Can you explain what event bubbling means in JavaScript?

• Please explain the key differences between the ES5 function and ES6 class constructors

Yes, our JavaScript coding tests can be customized for different experience levels, from entry-level developers to senior-level engineers. You can tailor the test to match the role and expertise you're seeking.

Universal coding tests prioritize problem-solving and adaptability over specific programming language expertise. By focusing on universal principles like logic and data structures, these tests assess transferable skills and encourage innovative solutions.

This approach broadens your talent pool, reducing biases tied to educational or socio-economic backgrounds, and welcomes candidates with diverse experiences and skills. It also fosters team diversity, creating a more flexible, resilient, and innovative workforce.
