Premium questions with real-world problems
The Ruby online test assesses candidates' knowledge of programming in the Ruby language.
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 Ruby native data structures and language constructs.
This online test requires candidates to solve coding problems in Ruby as well as to find and fix bugs in a Ruby program.
TestDome is trusted by businesses large and small

Free Sample Questions for Ruby Test
Our sample questions are free for companies to use on a trial plan. See more about our premium questions for paid plans below.
Merge Names
Implement the unique_names method. When passed two arrays of names, it will return an array containing the names that appear in either or both arrays. The returned array should have no duplicates.
For example, calling unique_names(["Ava", "Emma", "Olivia"], ["Olivia", "Sophia", "Emma"]) should return an array containing Ava, Emma, Olivia, and Sophia in any order.
File Owners
Implement a group_by_owners function that:
- Accepts a hash containing the file owner name for each file name.
- Returns a hash containing an array of file names for each owner name, in any order.
For example, for hash {'Input.txt' => 'Randy', 'Code.py' => 'Stan', 'Output.txt' => 'Randy'} the group_by_owners function should return {'Randy' => ['Input.txt', 'Output.txt'], 'Stan' => ['Code.py']}.
Pipeline
As part of a data processing pipeline, complete the implementation of the pipeline method:
- The method should accept a variable number of functions, and it should return a new function that accepts one parameter arg.
- The returned function should call the first function in the pipeline with the parameter arg, and call the second function with the result of the first function.
- The returned function should continue calling each function in the pipeline in order, following the same pattern, and return the value from the last function.
For example, pipeline(-> (x) { x * 3 }, -> (x) { x + 1 }, -> (x) { x / 2 }) then calling the returned function with 3 should return 5.

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.
