I found this an interesting topic. So many people do not know the difference between confident and cocky so this is the eternal question in leadership. The research that was done has a good sample and the results are what many companies should institute in creating a successful hiring environment.
“The findings mean organizations should proceed with caution before using hiring and promoting practices that cater to narcissists’ strengths. But, Harms said, they shouldn’t assume those with very low levels of narcissism are better candidates.” http://www.fiercehealthcare.com/story/do-narcissistic-ceos-make-good-leaders/2014-01-23#ixzz2wXFFXEAM
