Nothing is particularly hard if you divide it into small jobs
Henry Ford

I could have closed down bits of British Home Stores to make more money but it's not my style. I want to make my money as a retailer, not by putting people out of work.
Philip Green

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.
