Pros
Smart and collaborative colleagues across different functions, pretty much everyone I've met wants to do "the right thing", when it comes to serving patients, good work-life balance and fair compensation. The company is very international, but still has a bit of a "family feel" to it. Managers are actually concerned with respecting people's time off. The company has a great legacy and remains at the forefront of medical research, great basic commitment to innovation and people.
Cons
Career planning is up to how well you are at managing yourself in a decentralised matrix organisation. Can be a great opportunity, but don't wait for someone to offer you something just because you've been around for some time. Implementation is bottom-up, allowing a lot of room for new ideas, but making strategic decision-making long and cumbersome.
