JavaScript (coding): debugging

JavaScript debugging test: Pre-employment screening assessment to hire the best candidates

About the JavaScript (coding): debugging test

JavaScript is a flexible and powerful programming language that has been evolving very fast with the introduction of classes, generators, arrow functions, and many other features.

The ability to understand and debug code is a critical skill for a successful JavaScript developer. As new features are being developed for an application, bugs may be introduced into the code, and it is important for a developer to be able to identify and fix them. Given the collaborative nature of software development, it is also critical for developers to be able to work with and correct the code of others.

This test gives candidates a small script that contains one or more bugs. The description clarifies the objective of the code and provides examples to illustrate how it should function. Candidates must identify and fix the bugs.

We recommend combining this coding test with other programming tests such as Angular, React, Vue.js, Node.js, and SQL, as well as our tests on critical thinking and numerical reasoning.

The test is made by a subject-matter expert

Bereket G.

Take a bachelor’s degree in electrical and computer engineering, combine it with a mastery of HTML, JavaScript, and PHP, and add international experience in web and software development, and you’ve got Bereket. When asked what really makes him tick, Bereket describes his passion for developing web apps from scratch—from back-end REST services to front-end user interfaces.

What is the difference between an assessment and a test?
An assessment is the total package of tests and custom questions that you put together to evaluate your candidates. Each individual test within an assessment is designed to test something specific, such as a job skill or language. An assessment can consist of up to 5 tests and 20 custom questions. You can have candidates respond to your custom questions in several ways, such as with a personalized video.
Can I add my own questions to an assessment?
Yes! Custom questions are great for testing candidates in your own unique way. We support the following question types: video, multiple-choice, coding, file upload, and essay. Besides adding your own custom questions, you can also create your own tests.
How do video questions work?
A video question is a specific type of custom question you can add to your assessment. Video questions let you create a question and have your candidates use their webcam to record a video response. This is an excellent way to see how a candidate would conduct themselves in a live interview, and is especially useful for sales and hospitality roles. Some good examples of things to ask for video questions would be "Why do you want to work for our company?" or "Try to sell me an item you have on your desk right now." You can learn more about video questions here.
Can you explain how the other custom question types work?
Besides video questions, you can also add the following types of custom questions: multiple-choice, coding, file upload, and essay. Multiple-choice lets your candidates choose from a list of answers that you provide, coding lets you create a coding problem for them to solve, file upload allows your candidates to upload a file that you request (such as a resume or portfolio), and essay allows an open-ended text response to your question. You can learn more about different custom question types here.
Can I customize an assessment with my company logo and color theme?
Yes! You can add your own logo and company color theme to your assessments. This is a great way to leave a positive and lasting brand impression on your candidates.
