Pros
If you have some smarts and are ambitious, this is a great place to start a career. Promotes from within. Lots of opportunity to showcase talent and lead impactful projects if you are willing to put in the work. Those who excel at their job can be promoted quickly. Fun atmosphere, team building activities/events, lots of really intelligent people from all over the world to learn from. If you are looking for an international environment, this is the place.
Cons
The work itself can be challenging. You are dealing with high level executives who have a lot riding on a successful outcome. The regulatory world is not easy to navigate which makes the learning curve a steep one. You have to be committed to your own success and take time to continually learn.
