Opportunities for advancement are decent for new-hire, individual contributors for the first 5 years.

Advice to Senior Management

Pick something you want Symantec to be the best at, and execute to that goal. Being the most diverse, least integrated conglomerate of little software companies in the world does not count as a goal. Best consumer anti-virus company, or best enterprise storage software company are valid goals. Execute toward one of those goals with innovation, action, integrity and respect, and customers will reward Symantec with market share.
