Pluspunten
Market leader, decent product making a difference to many folks out in the world. It depends which team you get into but if you stay away from the politics then you would be fine. Great place to start your career, even better if you could start at a senior level ...
Minpunten
Soul of the company has changed dramatically in the last few years. All the old timers have left, It has become too political with new people coming into Senior Management. Too much churn, not much value for old timers. Longer periods of time there will not get you very far (does not matter how smart or talented you may be). The right folks don't get the recognition and promotions often go to someone not deserving initially - only when the promoted candidate makes a fool of himself/herself is when common sense prevails - it shouldn't be that way to begin with.
