When hiring people, what are you looking for? Knowledge about your industry, high IQ, many years experience? All these personal traits are important, but not as important as EQ – emotional intelligence – which means people who have natural warmth, are optimistic and can empathize with the plight of other people.
Who would you rather deal with, someone who seems cold and distant, or someone who understands your problems and can suggest solutions or ideas on a services/product level, but also on a more emotional and beneficial level. It is with everything else in life, we like dealing with friendly and warm people.
So when you hire, ask about faults, ask about being told off for getting something wrong, ask how they felt when someone else got told off at work? Listen to their answers, if they have no faults, if they never make mistakes, or think others are just not good enough, than they are obviously perfect.
Never hire perfect people, they are deeply flawed or inhuman, and nobody will want to deal with them, including you! ST.
