Saracelicia,
I sincerely apologize to you and the hundres (dare I say thousands) of people I failed to send followup/rejection letters to. My excuses are many but mostly invalid.
I had a small business. I usually had a steady stream of people applying for jobs and therefore rarely had to advertise. But on the rare occasion I had to advertise for a job, it was because I was short handed. It was a last resort because when I advertised, I got hundreds of applications from people that were not nearly qualified, even on paper. If I gave them an interview, and if they actually showed up, most of them were obviously lying on their resumes. I would interview scores of people before finding one that deserved a second interview.
By time I found two or three people that deserved a 2nd interview, I have gone through so many applicants I can't even remember who they are or why I rejected them. And since I am already short handed, I just didn't feel I had the time to write a personal rejection letter. For one thing, I do think they deserved a personalized rejection. For another, I HATED writing rejection letters. So they just sort of went to the bottom of my absolutely HUGE to-do list. I never sent form letters because I could never come up with one that was appropriate (true).
I sold my business 3 years ago, but I still feel a pang of guilt about that. Especially when I hear relatives and friends relating storeies such as yours. All I can do is say that you just have to accept it.
So again, I apologize to you for all of those like me that failed to do the right thing.
