Is there some German/EU law that requires job postings to be available for at minimum one calendar month? Cause that spike at ~30-31 days is real conspicuous.
Or at HR people just defaulting to 30/60/90 days for the posting being automatically removed?
That means that the crash probably started in October and we started seeing it on the data at the beginning of November.
I guess a large majority of those postings go unfilled.
Do you do any work to try to find if a position has been re-posted and recombine it with its previous posting for the purpose of this calculation?
I say that since they seem to remove them (presumably because they got enough applicants or actually hired someone) before the 30/31 day mark.
