I'll admit that my vision is blindered because I live in SF, lived in the Miami area, am a liberal, and work in technology. This. For people who are dis-advantage or of the mediocre-middle, these things are much more damaging. A strategy of playing confident in the interview, for example, is worthless if you resume gets auto X'd before anyone reads it or extends you an offer to interview. The audience for this (crap) is HR and BigCo types and other SMEs that are understaffed that outsource hiring to consultuants. Ie, the group of people that will not understand any subtle technical distictions about what makes a good engineer or not, anyway.
