Use of JavaScript (coding): intermediate-level algorithms test

The JavaScript (coding): intermediate-level algorithms assessment evaluates a candidate’s ability to program a small algorithm in JavaScript, testing their basic programming skills. Designed by subject matter experts, this skills test helps you identify developers with the most essential JavaScript skills objectively.

JavaScript is a widely used technology for creating dynamic and interactive web pages, and is the foundation of many popular frameworks like React, AngularJS, Ember.js, Vue.js, and Node.js. For junior programmers, it's essential to have a strong foundational knowledge of programming in JavaScript, which can help them hit the ground running and set themselves up for professional growth.

This coding test assesses a candidate’s ability to program a small algorithm in JavaScript, testing their basic programming skills. Some test cases are available to candidates during the test to help them determine if they are on the right track, while others are used once the candidate's code is submitted to check whether the solution resolves all the requirements outlined in the problem.

This is a great initial screening test that allows you to effectively screen candidates based on essential skills. We recommend combining coding tests with at least one cognitive ability test evaluating numerical or analytical skills to get a more comprehensive assessment of the candidate's abilities.

Intermediate-level algorithm

Intermediate-level algorithm skills in JavaScript involve solving more complex problems by implementing various data structures and algorithms. This includes topics such as sorting algorithms (e.g. quicksort, merge sort), searching algorithms (e.g. binary search), dynamic programming, recursion, and more. These skills are important as they allow developers to write more efficient and optimized code, improve problem-solving abilities, and handle a wider range of programming challenges. Mastering intermediate-level algorithms in JavaScript can greatly enhance a developer's ability to write high-quality and performant code.

The JavaScript (coding): intermediate-level algorithms test is created by a subject-matter expert

Testlify’s skill tests are designed by experienced SMEs (subject matter experts). We evaluate these experts based on specific metrics such as expertise, capability, and their market reputation. Prior to being published, each skill test is peer-reviewed by other experts and then calibrated based on insights derived from a significant number of test-takers who are well-versed in that skill area. Our inherent feedback systems and built-in algorithms enable our SMEs to refine our tests continually.
