Of the 4, only one is asked to do what they do during the interview. Event writers submit existing copy. Or at the very least, prepare it ahead of time before submitting it. Actors auditioning know what they are auditioning for before hand. They can prepare.

Programmers, however, must take a test. It's not an interview, it's a test. Pass or fail (regardless of what people say), it's a test. It's a test of which you have little preparation for. You hope that what they are looking for is what you can provide. What they are asking for is what they will test for (this is fairly often not the case).
