Well, I understand the point, but as an applicant you DO have the luxury of applying to hundreds of jobs, and at least when I'm applying, I'm trying to weed out potential employers just as much as they are trying to find the best candidate. So, I stand by my point.
Actually, all my job applications are "here's what I think" sort of applications. I don't much care about complying, only showing who I am. Yes, I didn't get some jobs and probably some of my applications DIDN'T help much, but looking back, I'm glad I didn't get those jobs anyway because in the end after hundreds of applications I ususally found something that was more my style.
