Pros
The opportunities for training are very good; they definitely encourage you to develop and take advantage of courses as much as possible. The variety of projects and sectors that the company works on means there is always some means by which you can further your knowledge or ask someone for some help when needed. The company culture is a dynamic one and staff are encouraged to strike a good work/life balance.
Cons
Because of the size of the organisation, there is an occassional risk of being put into a silo, thus lusing the broader feel of the company. Decision-making with regard promotions and workload for staff at the same level seems to be disparate and opportunities for increased workload are often down to the luck of who you are line managed by rather than anything else.
