(PHB) We all know someone like this, I'm sure...

The worst kind of interviewer is the blowhard. That's the kind who
blabs the whole time and barely leaves the candidate time to say,
"yes, that's so true, I couldn't agree with you more." Blowhards hire
everyone; they think that the candidate must be smart because "he
thinks so much like me!"

Nice article. Apparently a legend of some sort; got turned into a
book too! I'm not sure I agree 100% with everything he says but
there's no question he writes well, so give it a shot.
