This is the resume the author is linking in the article: https://www.dropbox.com/scl/fi/v2sv6ev393z9fkk62v1hw/Paul-Fu...
I wonder, if this person's main method of applying has been online forms where you click the "upload resume", he puts this resume in and then everything fails from the start because the ATS is unable to read it. It looks like the text in the resume is not text but an image.
I read some posts back this year that most publicly advertised positions get bazillion applications, most of which suck, so you have to assume a computer program is going to filter your resume first, unless you've been referred in.
I don't like his resume that much, I think it's a bit too embellished but if I needed a person with his kind of experience (based on the resume), I would talk to them. But if I also had 2000 other applications in front of me, I am not going to read them one by one without using a helper tool to filter them.
