And my favorite way to catch these people in the interview process is to ask the question, "Can you give me the names of four people whose careers you have fundamentally improved?" The takers will give you four names, and they will all be more influential than them, because takers are great at kissing up and then kicking down.
Los oportunistas le darán cuatro nombres y todos serán más influyentes que ellos, porque los oportunistas saben engatusar y luego dar una patada.
