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.

Just about every cover letter sent in response to an ad begins in the following style, "To Whom It May Concern: This letter is in response to your ad in the National Business Employment Weekly for . . ." Rather uninspiring, isn't it? Is it any wonder the few individuals who research a company, then use the information to formulate their cover letter's f irst paragraph, have a tremendous advantage over their complacent competitors? In the resume derby, everything you do to distinguish yourself moves you another length ahead of the pack.
