Sorry to hear that, charmingman, but I'm afraid it's rare to get a thanks-but-no-thanks for a lot of jobs these days. What sort of work are you looking for? And what are you doing to ensure that your CV stands out from the rest?
In medicine it has always been thus. Only after an interview would you find out if you'd been accepted or rejected. Except for recently where we're having to rely on a free forum to find out if jobs have been offered at all some 3 months after the first round of interviews.
It's plain rude not to let someone know their application was unsuccessful. Everybody who is recruiting has, at some stage, applied for a job, so they should realise what a positive difference a little courtesy and communication can make in reducing stress.
I was job-hunting in 1971, having just returned to UK after some years overseas. I'd applied for several advertised jobs and was becoming increasingly annoyed at the number of firms who couldn't be bothered to respond. That's just bad manners.
However, please don't be tempted to do what I did, namely chuck Teddy out of the pram and write an ill-tempered letter to the most recent offender.
That letter did produce a response — from the firm's managing director no less. I still have his note. It says: "Sir. We have not yet compiled our shortlist of those we wish to interview for this position. Be assured that your name will not be on it."
