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.

Palindrome

CODE

Ruby Strings Public

A palindrome is a word that reads the same backward or forward.

Write a function that checks if a given word is a palindrome. Character case should be ignored.

For example, is_palindrome("Deleveled") should return true as character case should be ignored, resulting in "deleveled", which is a palindrome since it reads the same backward and forward.

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']}.

Path

Write a function that provides change directory (cd) function for an abstract file system.

Notes:

  • Root path is '/'.
  • Path separator is '/'.
  • Parent directory is addressable as '..'.
  • Directory names consist only of English alphabet letters (A-Z and a-z).
  • The function should support both relative and absolute paths.
  • The function will not be passed any invalid paths.
  • Do not use built-in path-related functions.

For example:

path = Path.new('/a/b/c/d')
path.cd('../x')
puts path.current_path

should display '/a/b/c/x'.

What Others Say
TestDome user reviews on G2 Crowd
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.

Jan Opperman, Grindrod Bank

Very smooth, well supported, great for assessing candidates

Very Prompt and helpful support when needed, we were looking to work with a third party to write and set up new tests, TestDome was able to quickly set up and support a method to do this, allowing us to start testing candidates straight away.

George Offer, Guided Solutions

Easy to use and efficient for testing developers of different levels

It provides us an opportunity to set our own timing policy, to choose from variety of questions from different areas and with difficulty gradation. Also it is great that TestDome provides free of charge tests for candidates to prepare and check how online IDE works. And support is always ready to help:)

Screening Applicants: The Good, the Bad and the Ugly

Since we’re all biased and we use incorrect proxies, why not just outsource hiring to experts or recruitment agencies? After all, they’ve been screening people for many years, so they must know how to do it right?

Not really. I was surprised to discover that many experts disagree with each other. Everybody praises their pet method and criticizes the others. Many of these methods look legitimate, but are based on...
