What makes it so great?

Every other month, Cisco CEO John Chambers invites employees whose birthdays fall within the designated two-month period to an informal Q&A with the head honcho himself. Those not located in its sunny San Jose headquarters can join the chat via Cisco TelePresence locations and TV broadcasts.

The company also offers job sharing, onsite childcare and, in France, pre-first day training. Through an interactive website, new employees learn all about Cisco's mission and its culture, allowing for a smooth transition on the first day. This type of training is representative of the management chops the company boasts.
