Pros
The culture at CSC is one of the highlights - if you ask for help, people willingly give it, and generally, everyone is very nice. Its also quite a relaxed environment and not overly formal, perhaps too relaxed for some. Another pro is the fact that there is a great deal of flexibility - one day you can be working in Business Development, the next in Delivery. You have a lot of control over your own career.
Cons
I was employed by CSC to be a business analyst, but I have done hardly any typical business analyst type projects or ANY training. CSC is not yet committed to trying to compete in the pure-play consulting arena, although I think Lawrie is trying to change this. The last few years have been tough - no payrises, bonuses or training for the majority of people.
