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.

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.

# Adds a required css class to the label if the field
# is required in the model using a presence validator

# You need to place this in a file that will be autoloaded
# or required manually into your project. The initializers
# folder is autoloaded, but you might already have a better 
# place where you load in similar things for your project.

# Add this to your css:

UPDATE: It's a gem!

This helper has finally been moved into a gem called nav_lynx!

http://rubygems.org/gems/nav_lynx

Thanks to @brianjlandau and @reagent for getting that set up and tested!

Behold, the nav_link:
