# Let’s consider an example. We will add the models as they are required. Right now the basic application has models User, Role and Permission. The relationship is as shown

Role #the model to save the role
  :name                 # the role name
  :has_many :users
  :has_and_belongs_to_many :permissions

User
  :name       # user name
  :email      # user email

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](http://www.tobi.com/), 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.

## What to expect

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.
