Pros
If you are a junior software engineer you can expect some decent mentoring and guiding in your career development. There is a dedicated education program which you can use to develop your professional skills and profile. For the most part there is a good working atmosphere.
Cons
Once you get to middle management you will get stuck and its really difficult to accomplish anything. No clear responsibilities, and many of the people in middle and senior management like to keep the status-quo and be surrounded by yes-men. While the company preaches how much it cares about its employees, its all a facade - neither HR nor senior management show genuine care unless it benefits them somehow. Swiss colleagues, including management, can be judgmental / prejudiced of employees from other locations.
