Ah, so you found one that you disagree with. I see you didn't go far because that was the fourth one on the list. But if you scrolled further down the page, you'd find well over 100 videos of resume writing and services that provide resume services. I stopped when I got around 100 because I don't have time to count each and every one, but I'd be willing to bet there are hundreds of them, and you're not going to convince me that none of them can't teachl people to do what you do.
Actually, you miss the point entirely... YOu could probably figure out how to write something that looks like a resume listening to one of these people. (Actually, most of her advice was kind of shallow). What you won't get. A resume that makes people call you back for a job interview.
That's the only purpose of a resume, to get you a callback for an interview. If you followed most of these DIYers, you wouldn't get past the ATS system, much less into the hands of a human.
