Maybe people wouldn't do this if applications didn't go into a black hole to either never get responses or get responses months later. Out of all my job searches I've only ever gotten one interview by applying with a company instead of working with a recruiter. If you only interview candidates from recruiters why bother posting the job on sites like Linkedin?
So the applications are made via A.I, then read via A.I (at least in the case of the major job sites, e.g seek and linked in).
I agree with the poster that this shouldn't be necessary, and is usually done by candidates who don't seem to realise the actual problem (usually themselves), but the recruiters have some blame in applying the same system to read the applications.
As a side note, is this becoming one of the first pure A.I information businesses? Given you can mimic voices and video via LLM, you could start going to interviews via A.I generation too...
