Hi All,

Recently i've been tasked with conducting short interviews with
potential contractors who would help our team with some rails projects. I
am limited to a ~30min interview via IM (most of the time the guys are
located in a different country) and i have to tell my manager wether the
contractor seems OK for our project or not.

I know there are tons of great articles on how to conduct interviews etc.
However i only have 30mins of IM to determine whether a contractor is a
good fit for the project or not.

Right now i usually ask them about:

   - some ruby fundamentals
   - some rails fundamentals
   - what projects have you worked on
   - what are some gems you are familier with and what do you think about
   them (pros and cons..etc)

But i feel that i am not getting a true sense of their experience and
abilities through these questions. And most of them don't have any open
source contributions..etc for me to take a look at.

So i wonder what others do when they are looking to get some external help?
how do you see if a specific contractor is a good match for your general
rails project?

Thanks!
