This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

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.

##What is Rails?
Rails is an open source web application framework written in Ruby. It is a full-stack framework that has been optimised for programmer happiness and sustainable productivity. It emphasises the use of well-known software engineering patterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), the active record pattern, and model–view–controller (MVC).
Extra: David Heinemeier Hansson (DHH) is the creator of Rails, having extracted it from his work on Basecamp. He first released Rails as open source in July 2004.

Classes are a blue-print, they may hold data, likely they hold methods; classes are directly connected with an idea of objects, because object is an instance of a class. As objects are first-class citizens in Ruby, there is a main, root class Object, and all classes are inherited from this root entity. Modules, generally, are a tool for mix-ins and they provide something we call a namespace. Modules cannot be initialised the way we can do this with classes, but they provide a multiple inheritance.
