Here'a a recent case for a remote software engineering role for a US based company:
A position is posted publicly, in 2 days it gets 300 applicants. Out of those 300, 9 are selected for interviews. Of the 9, only 2 showed up for the interview. Both candidates weren't close to a good fit (skills didn't match resume, etc.).
It opened my eyes on the process. Imagine an engineering manager getting handed a few hundred resumes and now they need to hand select ones that move onto the next phase. This takes a huge amount of time and it also indicates if your resume isn't strong, you will probably get passed over in a few seconds.
With that said, he told me most of the applications were AI spam.
