Pros
Old glory of networking protocol patents and acquisitions (of IP) is pretty impressive
Cons
This is by far the worst place I have worked. I have been in silicon valley for 2 decades and worked at many places. Joined Cisco recognizing it will be a great place. Hardly. Not sure if only my Manager but he was a jerk. The communication between groups & within groups is awful. There are many cliques and if you fit into one of them, it does not matter what you do - you will move ahead. The source code is not shared between groups - meaning you have no access to the source code or their design documents of the group you are working with. You can get it through unofficial channels through acquaintances. Remember cliques. Many details are kept secret and internal management conflicts are too much. The management in many cases is unethical and force you to work on weekends. Hire cheap labor from abroad and ask you to train them. This is the only place where I noticed the Manager expects the outgoing person to work until his/her last day. Above all, the technology they are working with is dated is not worth staying here for anything. Unless you can't find a job anywhere else.
