The recent thread about reposting of jobs made me think of my experiences over the past several years. Someone said it was rude of an employer not to tell someone they did not get a job, but in my experience, this has been the norm for the past 10 years or so, much worse in last 5 years. At least half the time, no acknowledgment of any kind, even after an interview.
I was taking it personally, but my 36 year old son told me this was the new norm.
