Do employers do this just to see if you're willing to jump through hoops for them? I'm convinced its a combination of this and just bureaucratic inefficiency.

They do it because not everyone formats their resume in the same way. Lots of people also fail to include important information or save as a PDF. I've read some truly horrendous CVs.

This form will ensure that the hiring manager can look through applications more easily as all the information will be in the same format and every candidate will be giving the same pieces of information.

When they find candidates that interest them, they'll read the resume.

The person reading this nonsense and the person who decides to use this system are different. You aren't "sticking it to the man". You're just giving a completely different person a reason to be annoyed with you.
