Under US labor laws at least, you only have to pay someone if they are doing work that benefits the company materially somehow. They would be forbidden from grabbing bugs out of their queue and saying, here go fix this and maybe we'll hire you. Same with unpaid internships which are _supposed_ to be training and shadowing opportunities only, no actual work being done.

That said, I did just peek and my notes and I read that candidates are paid two week's salary for the coding assignment.
