Premium questions with real-world problems

The (Ruby and) Ruby on Rails online test assesses candidates' knowledge of programming in the Ruby language as well as their knowledge of the Ruby on Rails web application framework.

It's an ideal test for pre-employment screening. A good Ruby developer should not only be able to solve problems using Ruby as the programming language but also be familiar with the concepts behind Ruby and have commonly used Ruby on Rails APIs, which makes Ruby on Rails development quite different from desktop or server-side development.

This online test requires candidates to solve coding problems in Ruby and answer questions about the Ruby on Rails web application framework.

TestDome is trusted by businesses large and small

Pass/fail grouping

Our tests are designed to put candidates into either the pass group or the fail group so you can find the best candidates faster.

Full customization

We have pre-built tests and questions, but you can customize them however you like. Change the pass/fail scores, time requirements, and more.

Cheating protection

Use tests that solve real-world problems, with no answers that can be easily found online. Because we test performance and skills (not information), we allow the use of online resources, just like in real life. Copy/paste prevention and online proctoring via webcam prevent cheating.

Candidate reporting

Get an overview into the percentage of passes and fails. Then dive deeper into the results of your top candidates to select who goes onto the next phase of hiring.
