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.

Updates

This document was published on 21.09.2015 for a freelance employer. Some changes since then (14.02.2016):

1. Koa.js no longer uses co-routines, it has switched to Babel's async/await. yield and await are used almost in the same way, so I see no point to rewrite the examples.
