Pluspunten
I you are looking for a friendly and non-threatening work environment with a stable, 40-year-old IT company (not many around anymore), Software AG is your kind of place. Software AG has allowed me to try on different hats (or "tours of duty" as they are sometimes called) during my tenure, and that has been a rewarding experience. You can do a whole lot worse than working for Software AG, and that's perhaps why many employees stay around for decades.
Minpunten
If you are looking for an exciting, fast-paced, team-driven, cutting-edge workplace with lots of pressure and long hours, you might want to look elsewhere. Also, if you are looking for a company that invests tons of money in technical innovation and marketing, you will **definitely** want to look elsewhere. One of Software AG's core competencies is cost control (how does an IT company stay around 40 years?) leading to long-term profitability.
