Pros
Cisco is a great name to have on your CV. Represents a good opportunity to meet lots of big customers and do some big deals.
Cons
This is one arrogant company. The general view is that we should feel very lucky to be here, and that staff are expendable. There is no real opportunity to progress, you can only get on by sucking up to the right people. Praise for doing a good job does not exist. The company is making the job as hard as it can in a tough environment, in the hope that people walk, as they have over recruited already and don't want to make people redundant. UK management team are not industry leaders, just yes men to the US and only understand management metrics for monitoring staff. The people who have been doing a good job successfully for years get over looked and taken for granted, while the self promoting "connected" brown nosers get promoted. Was once good, now like every other big slow arrogant beast.
