1. You still need resume filtering because any public req will receive literally thousands of resumes most of which are poor fit. And that's after HR software did its thing btw. Can't spend 20m on thousands of applications most of which are low effort slop sent by folks who aren't even committed / competent enough to read and follow the req. This was already an issue 10 years ago before AI so I imagine it's at least 10 times worse now.

2. Once you're past that point, at least in my personal experience conducting hundreds of these sessions, most people are pretty bad at going into any kind of depth on stuff listed on their resume so your best strategy (that is if you want to hire anyone at all) is to ask generic questions that are role specific. At best you can tailor some of them to what's in the resume.
