Pros
CV is very good at helping you maintain a work/life balance and is open to allowing you time out for appointments or working from home. There are few airs and graces, upper management are willing to chat to shop floor employees. Good ideas are acted upon and rewarded via an engagement scheme. You are trusted to get on with your work in a relaxed and friendly atmosphere. The work is straightforward, not really challenging and it's easy to leave your job at work and forget about it, I've heard it said that CV are great at jobs but not careers, so if this is what you are after then CV is definitely for you!
Cons
There is virtually no internal promotion prospect, unless you're in upper/middle management where new jobs seem to materialise regularly, once they're given to someone. I've applied for 4 internal positions (two of which I was recommended to do so by the recruiting manager) only to see the jobs go to external candidates. Even if promotions do go internally they are often "given" and announced rather than openly advertised. The company talks a good game of investing in employees but rarely seems to deliver. Also the company has an unusual understanding of "Global" roles, these are only available to you if you've got a US-focussed mind-set and live in the USA.
