Yodle Yodle/Software Developer interview questions

They have two programming exercises, the harder one is a programming challenge where you have to place jugglers in their preferred circuits. I spent a few hours programming it and got the correct solution, and you e-mail your solution and resume to the e-mail address based on your answer. The e-mail just goes straight to HR, you don't bypass them. All I got was a disinterested reply saying they'll pass my resume to managers and see if there's any interest. You don't get an automatic interview as the challenge sort of implied. Oh well.
