I'm dreading the day I need/want to look for another job!

That said, there may be contexts where their advice would help. It's likely useless in all organizations that have a human resources department, since they will be dictating policy and may even be doing the initial screening. But smaller businesses? Quite often their handling of applications isn't all that different from my grandparent's day. Replacing that emailed resume with a hand delivered one may be enough to get their attention.

I also wonder how applicable modern approaches would be in towns and smaller cities. Something tells me they would rather only deal with local candidates and not have a bunch of people who apply from out of their area.
