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.
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.
