This looks great!

We've been trying to improve our interview process and I think this sort of tool would help us out a lot. I'd be very interested to see if you could like to something like Project Euler on the interviewee's side in order to show what they can do outside of a timed question.

Also the demo page needs needs to have links associated with test, create, select. That's just a personal thing but I like icons to have associated links.

Edit: I activated my account and toyed around with it a little bit. I think you should have sample in the Question->Preview section. I'd also like to see functionality to take my own test. It looks great though.

This is my first non-trivial side project and I'd love some feedback on it. What do you think of the home page, concept, etc. Any suggestions?
