Nice one! And it's probably good for you also as it helps you draw a line under it by giving it away.
I should be a target customer, since I periodically interview candidates for programming positions. However, landing page and screenshots failed to explain to me what the unique selling point was. How many people here know what "Feedback-Driven Interview" is?
Whole product seems to be about providing an online testing tool ala topcoder.com. But coding tasks are usually only a small part of the interview process (not that I agree with that, but that's what happens at 90% of companies I've applied for).
