Exactly. Too-honest people are exactly the ones I want to hire, because they're way less dangerous once hired. An important part of any interview for me is testing somebody's willingness to bluff or BS. A little's perfectly normal, but too much is an immediate no-hire for me. An employee who covers things up to look good can cause enormous problems in a high-trust environment.

They said that the very worst hires ace those questions. They did not say that everyone who aced the questions (and was hired) was a bad hire.
