The day that I'm giving candidates extra credit for using nice paper or high-quality ink or sending an application by Priority Mail is the day that someone needs to ban me from hiring, because I'm no longer doing my job right.
My job is to discern who the best candidate is. At best, gimmicks don't matter. At worst, they get in the way or even hurt. At least if you're dealing with someone who's good at their job (which, admittedly, you may not be).And here's an additional point: If you get a job by using a gimmick to "stand out," you've just self-selected for a manager who responds to gimmicks over merit. Is that the place you want to work?
I think we're in danger of this gimmick issue becoming my new rant, right after companies that don't respond to job applicants.
