As someone who is still technically waiting - after a month - for his phone interview, I like the idea of doing some actual coding. If you have to make people jump through hoops, at least you might try and make the hoops at least somewhat meaningful.

Edit: I just pressed the button on my TripleByte dashboard to switch to the "project-based" track, but then I get redirected straight back to the same "we're sorry" page I've been seeing all along.
