It's just a job. Grass grows, birds fly, waves pound the sand. I just beat people up
Muhammad Ali

A great resume can get you invited to the penthouse, where your masterful interviewing techniques will lead to a great opportunity complete with a substantial raise and a covered parking spot with your name on it.

Replying to all resumes would be the polite thing to do, but often it simply isn't practical. If a company receives 200 responses for an ad, or experiences a continual deluge of unsolicited resumes, it would spend an inordinate amount of time sending acknowledgments. If you really want a receipt for your resume, send a stamped, self-addressed postcard asking for one. If you make it easy, the human resources department will comply.
