Cisco has the stereotype (at least here in the South Bay) that it has almost only Indian employees. There is also the idea that since Cisco hired so many Indians, it is now no longer considered an American company (I don't seem to be able to find the link anymore). Finally, there is the rumor that Indians only hire Indians. So after all these stereotypes you would think Cisco would have an Indian CEO.
