Worked at a place hired one of those. He scheduled meetings, then cancelled them at the last minute. Never accomplished a single task. Demanded a good reference and he would go get another job elsewhere - essentially extorted the reference. I guess some folks are sociopaths, and do whatever it takes to live well.
