Interviewing for integrity will sift out job candidates who've mastered the art of embellishing their qualifications, fabricating stories, and flat-out lying. Not interviewing for integrity is especially risky during periods of fast growth or high turnover, where hiring managers become desperate to fill positions and rush to judgment by overlooking unwanted behaviors and toxic personalities. Buffett is well-aware of this fact, which is why he places a premium on integrity, and so should you. But first, as a hiring manager or a person who conducts interviews as part of your job, you have to master the science of interviewing to validate skills, strengths, and job fit on the basis of fact, not theory.
