I'm not sure that this effectively replaces any part of the traditional process (resume--phone interview(s)--onsite interview(s)). I guess it comes closest to replacing the phone screen, but my understanding is that the goal of the phone screen is to establish "can this person actually write code" which I don't really think this does given how easy it would likely be to cheat--either by finding a solution online or by getting someone else to do it for you.
