Are you a hiring manager/recruiter in tech? In this Circus Funhouse Mirror tech economy, how do candidates even get an interview?

I've been a hiring manager before across a few jobs. But, then, I was receiving maybe 50 resumes to screen a week with my recruiter. Y'all are, what, at a few factors to an order of magnitude more than that?

Are your recruiters now pre-filtering resumes before you see them? What is being used to determine whether a candidate gets an interview now?

What I'm seeing:

• Referrals almost never matter: I've gotten two interviews through my network after dozens of applications—and I'm fairly well networked.
• Experience at other well-known Tech companies doesn't get an interview
• Having the right skill set, based on the job description doesn't get an interview.

From the outside, it seems like a coin flip.

Meanwhile, I have LinkedIn's AI advisor routinely giving me flavors of "yes, you're definitely their kind of candidate" yet no responses after weeks followed by the occasional casual rejection email.

So what's happening behind the scenes? How do resumes get on your radar? How do you work from the deluge to hiring a human?

Sincerely,
A very experienced engineer and manager who is rather fed up with what seems like a collection of pseudo-random number generator contemporary hiring processes.

EDIT: I should have also included recruiters in the title of my ask.
