I have trouble believing you aren't being facetious, trolling, or willfully ignorant. If you've spent any sort of time in this industry at all, you know that people apply to many places at once. Sure, one 10-hour assignment isn't much, but although you seem to live in a fantasy world where people only apply to (and receive) one "job application homework assignment" at a time, that's not actually how the real world works. Companies that tend to pull such nonsense also tend to have poor work cultures. I suppose it self-selects for people who don't have a family or out-of-work commitments, but maybe that's what they're going for.
