However, if you ping me on my profile email after I put up a job on Who's Hiring, and I send you back an email saying "hey, can you answer these few filter questions, take your time" and one of them is "what is multicollinearity", chances are you'll google it and tell me what you typed above and it will be fine. It's not like you can't use Google or take your time.
What I'm dealing with is people who are dumping their CV and a standard cover letter on me at high frequency and I do not want to put an HR filter between them and me, because I want to spot the guy without a LinkedIn profile (HR red flag), who dropped out of college (so no brand - HR red flag) but has plenty of useful experience (so no buzzwords, because real experience looks unremarkable on a CV - HR red flag). I know no more efficient way. Would love to hear of any.
I did make the mistake many years ago of rejecting a PhD in stats because she admitted not knowing about neural nets ("but my lab buddy is doing some research in them"). I'm still kicking myself, but have learnt a bit about hiring since then.
