A competitor who has come up with a different approach to the interviewing challenge is http://codeeval.com/

Their approach is different/beyond watching the candidate code.

Wow you can create your own challenges? That's awesome. I've seen some sites like this before, but they usually have a predetermined amount of algorithms.

I always wanted to make my own challenges that would have to be automatically solved by potential candidates, and here it is! Glad someone else did this already.

Edit: I see codio.com does this as well
