Pros
A company that offers a lot of different careers within the same organisation. High performance culture that will reward constant effort and respectful behavior. There are good benefits and performance bonuses. The executive leadership team is experienced and recognized all over the world for their competence, their strategy and corporate reporting. Also, I never worked in a better company in terms of the overall respect and cooperation that employees show to each other. It's surprisingly easy to talk honestly to your support person about how you feel and your career goals too. Everybody is working towards the same goal: excellence in client satisfaction & profitable growth!
Cons
As the organisation gets larger, there is sometimes heavier bureaucracy. Lots of forms to fill out for anything that you're looking for. Because the management also cares a great deal about investors & the share price, naturally, there is also very tight budget spending, and sometimes exciting projets will be pushed to the next year in the name of cost control.
