Marissa Mayer was an engineer before becoming an executive. Was she? Her career essentially started at Google, her rise arguably being one of right place/right time. For all of the talk about Mayer, I have literally never heard about anything actually interesting that she has done. Instead it's her 90 hour work weeks, n-shades of blue, and abrasive attitudes with others. She sounds like management through and through.
