When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.
To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.
Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

# Install the MYSQL driver | |
# gem install mysql2 | |

# Ensure the MySQL gem is defined in your Gemfile | |
# gem 'mysql2' | |

n = Notification::Answer.new | |
n.class.name.split('::').last || '' | |
# => "Answer" | |
n.class.name.split('::').first || '' | |
# => "Notification" |
# Recursively diff two hashes, showing only the differing values. | |
