15 Questions to Ask During a Ruby Interview
View gist:5252653

Originally published in June 2008

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.

AWS SNS Sample code.
View _sns_description
Notes on how to use AWS SNS:
1. Subscribe an HTTP endpoint (i.e. http://myhost/sns_endpoint) on AWS Console
2. AWS will send subscription confirmation right away
3. SNS_controller responds to subscription confirmation by sending confirmation using Fog.
4. Once AWS is happy, you can start sending notifications to your end point via SNS.
