It might also work if the audition was applicable to many potential employers, like how talent scouts in sports and the arts go to events where the potential talent performs rather than having the person audition for each potential employer. (I'm not an expert on arts or sports so I might be off on my analogy.)
I hear a lot about GitHub, blogs, and open source contributions which essentially act as your audition open to all talent scouts.
Perhaps if the audition challenge could be posted to the applicant's GitHub account then it would be a bit more useful to the applicant. The challenge could be skipped if a project in the GitHub account already demonstrates proficiency in the desired application domains.
The sports analogy is partially correct, but college prospects in all the major sports have to go to the talent recruiters before they are signed. (NBA tryouts, NFL Combine, etc.)
