They never acknowledged my stuff either, way back in the WAWZ days w/ Rosetta Key, Bill Jones, & crew doing actual NJ news (pre-Star 99.1). I DID, however, receive a neat American flag decal & solicitation mail. Oddly enough, I was trying to pitch a Gospel/CCM format before they cleaned house & flipped.
If it makes you feel any better, the last place I applied (a public service station, non-Christian) sent me a nice, official "materials received" letter within a day after receiving my stuff. Interview was solid, they said they'd contact me within a week, & I sent a strong follow-up letter back that week. After I called three & a half weeks later, top dog calls back later that day: "I just wanted to tell you personally how impressed we were with you, but we went with someone else"... blah, blah, blah. At least mail me a letter to post (back in college, we'd proudly hang our "bullet" letters on our dorm room doors - from job opportunites that shot us down).
Oh well, Happy Thanksgiving, all! I am grateful for the opportunity to work at a place where what we do impacts lives. Peace. 8)
