A PRACTICAL GUIDE
Using JavaScript in recruitment.
What does the JavaScript test assess?
Questions cover language fundamentals, functions and objects, and how scripts interact with the browser and the page. It measures understanding of JavaScript through multiple-choice questions; it tells you who is worth a coding exercise rather than replacing one.
How can you use the JavaScript results?
Use the score to decide who gets a technical interview, then set a short task or a code review from your own codebase. Pair the test with a React, Angular or Node.js test for framework roles and a logical reasoning test for roles that design algorithms.
Which JavaScript skills matter for your role?
- Frontend developmentUnderstanding functions, objects and browser interactions.
- Application maintenanceReasoning about JavaScript language behaviour.
- Technical interviewsExplaining how a candidate would approach a coding problem.
Choosing tests for your vacancy
Choose JavaScript for knowledge of language fundamentals, functions and objects. Add React or Node.js only when the vacancy uses those technologies. Use a separate coding task to see how candidates apply the knowledge in your kind of application.

BEFORE YOU START
Your JavaScript questions, answered.
Do candidates write code in the JavaScript test?
This assessment checks JavaScript knowledge through questions. Add a practical coding task and code review when you need evidence of how candidates build, test and maintain working code.
Which JavaScript topics should matter for my role?
Start with the work the person will do. This page covers language fundamentals, functions & objects, browser interactions. Decide which of those areas matter for your role before reviewing results, and explore any specialist requirements separately.
Can I combine JavaScript with other tests?
Yes. Add JavaScript alongside other relevant tests in one assessment. Choose the combination for your role and review the total time before inviting candidates.
Can I assess real candidates for free?
Yes. Create your account, build an assessment and invite candidates. Your first 5 candidate results are free. No credit card is required.
What happens after my free results?
You pay per candidate result you unlock, rather than per test. There is no subscription or annual commitment. Check the pricing page for current rates.
How should I use the JavaScript results?
Compare results against the knowledge or ability your role needs. Use them to focus interviews and practical tasks, alongside relevant experience. A test score should not decide who you hire on its own.
