Saw this after opening my 12th "we regret to inform you". This seems like a solid alternative, considering recruiters won't even open up your resume anymore before running it through a machine.
I think all these "we regret to inform you" could be avoided. It has always felt weird to me that the burden of the search is on the candidates, although recruiters are doing the picking. It’s more efficient and less painful to just let people express their preferences and be applied to.
I've never really come across this kind of reasoning in practice, though. Companies that want the best candidates are more often than not keen to put in the work to get them.
