Shmidt wasn't a professional CEO, he was a software engineer who worked his way up the ladder and then took his experience as CEO to another company.

Tejada's experience seems to be all related to corporate management, and thus is a professional CEO.

She rocks at sales, and she knows how to push back corporate suits (keep them from interfering too much with engineering). She supports her employees over the shareholders. She's great.

That is the Jennifer Tejada I know.

Edit: You've edited your response so many times I can't keep up. I am not arguing any point of view. You unilaterally said that it is always a bad sign when a company brings in an experienced CEO. That is an ignorant stereotype. Sometimes they succeed, sometimes they fail. Sometimes it's a smart hire, sometimes it's not. The late Dave Goldberg taking the reigns at SurveyMonkey was an incredible turning point for the company.

I feel "professional" managers are bad for tech companies. Here are two reasons :

1. A lot of management techniques that are taught in business schools apply to traditional manufacturing based businesses. A lot of these underlying assumptions are invalid in the tech businesses.

2. Tech businesses require a deep understanding of what is possible with the current state of the art. This is requires a deep understanding of technology so that when there are fundamental changes to the landscape (which happens more frequently in tech) the company can adapt and stay relevant.
