If I could make a company send me a ding letter if they didn't like me then I would.
Personally I find it only fair. we spend the time to write the cover letter and set up our resumes, the least they could do is pop out an automatic ding letter. Or e-mail even. Considering that most companies get resumes e-mailed to them they have no reason not to do a mass ding letter send out.
I had an interview with Geico and I never heard from them. It's a little discerning to see how much companies care. And unfortunately this seems to be the norm for this day and age.
