  • Why is a Ruby On Rails test so important when hiring?

    It's essential for recruiters and hiring managers to use the Ruby on Rails test when hiring developers to use the framework.

    When faced with a pool of CVs from similar candidates, it can be difficult to determine who the best person or people to take forward are. But the Ruby on Rails test allows you to put candidates' knowledge to the test and see who really does have the skills and knowledge required to make it through to the next interview round and be successful in the role.

    Because Ruby on Rails is such a specific framework, it's essential that you use a specific test to check candidates are comfortable with everything from coding to action controller and routing.

    Tests such as these also provide an unbiased way to assess applicants and ensure that people moving through to the next round of recruitment are those who deserve to be there based on their skills, knowledge and understanding.

    The Ruby on Rails test is a suitable hiring device for the following roles:

    • Web developer
    • Mobile developer
    • Software engineer

How to assess Ruby on Rails skills using our test

Our Ruby on Rails test asks a variety of questions that vary in difficulty level. Candidates who are proficient in Ruby on Rails should be able to answer most of the questions correctly.

The Ruby on Rails test provides valuable data-driven insight into what a candidate knows and understands. The test is structured using multiple-choice questions: a familiar format for most test-takers, that allows for instant and objective scoring.

As well as the correct answer, there are typically 2–4 distractors, representing common misconceptions and mistakes. This helps make the test more challenging, so a candidate's ability can be measured more accurately.

Test scores are provided to the user and can be compared to other test-takers in your talent pool to see how they perform relative to each other.

Each test has been thoroughly reviewed to ensure accuracy and validity in line with industry standards. It has been written, examined and edited by Ruby on Rails experts and psychometric professionals. It has also been reviewed by a diverse sample of job seekers to check for any issues including sensitivity, face validity, fairness and accessibility.

This test is continually monitored so our team can optimize performance and regularly assess fairness issues.
