The main thing that changed since when this article was written is that companies are much less in a rush than they used to to hire people, which means that a lot of mechanics described in the article fall apart.
In particular, companies don't really look at how much they spend to hire someone. They'll just wait for the hiring committee to be "really excited" about a candidate before making an offer.
