Professions like pilots, doctors and CPAs are bad examples because they have a certifying body that exists outside of the relationship between employee and employer. It's true they're not getting paid for that certification, but once they have it, it's valid and transferable between jobs.

Musicians and actors are better examples, as they do have auditions, but lots of actors and musicians get jobs based on their previous body of work, rather than an in-person audition.

I'm curious, can you name more professions that use what is essentially auditions for hiring, besides artist-types?
