Pros
Challenging and interesting work, for the first 1-2 years. Interns and graduates are relied on to help deliver key projects. Colleagues are friendly and willing to help with questions. There are lots of sports opportunities - often more than one at each lunch time, and the office culture is to take a full hour's break at noon.
Cons
Slow promotions and requirement to fully prove capability before being allowed to move into new roles. Stubborn and inflexible management. Constant work overload. Constant changing of priorities, as events are often elevated to 'emergency' status unnecessarily. If you are not part of the lunchtime sports culture, then you are less likely to be given opportunities. Employees are rarely trusted by management with enough authority to effectively get their jobs done. No annual bonus (you usually get a Christmas turkey).
