It sounds like they've found a legal way of getting free work completed.

Is there some kind of signing bonus if you make it through the interview process and get an offer? I think there should be.

Yes, they must be making a killing getting people to build them cars for free in C++.

More seriously, it sounds like they go out of their way to avoid giving their applicants any work someone might profit from.
