The Ruby on Rails online test assesses programming skills in Ruby and knowledge of the Ruby on Rails framework. This test includes solving live coding problems in Ruby.
The assessment includes solving work-sample tasks, such as:
- Mapping database tables and relationships to Ruby objects.
- Configuring routing mechanisms.
- Solving coding problems given specific requirements.
A good Ruby developer needs a solid understanding of the Ruby programming language and commonly used aspects of the Rails framework in order to create robust, scalable, and user-friendly web applications.
Sample public questions
As part of a data processing pipeline, complete the implementation of the pipeline method:
- The pipeline 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 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 pipeline in order, following the same pattern, and return the value from the last function.
For example, calling pipeline(-> (x) { x * 3 }, -> (x) { x + 1 }, -> (x) { x / 2 }), and then calling the returned function with 3 should return 5.
Select all statements that are correct after the following migration has been executed:
class ContactsMigration < ActiveRecord::Migration
def change
create_table :contacts do |t|
t.string :name
t.integer :telephone_number
t.text :address, null: false
t.timestamps
end
end
end

What others say
Simple, straight-forward technical testing
TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
