This was a pair programming session with a Ruby engineer. They allow you to use your own laptop which was great but you only get 30 minutes to finish the problem with working unit tests. I think they re-use this pair programming problem so I'm not going to divulge details here. But it wasn't a particularly hard problem, they just want you to see how you code and test. Do not forget to write unit tests! Ideally you would develop it in a TDD fashion.
