Vantaggi
Great benefits, smart people. Great salary, great workplaces (SF or San Jose). Great food. Good addition of new talent via smart acquisitions in new spaces.
Svantaggi
Huge shifts in management. Near-yearly Fall layoffs (and nearly impossible to fire someone otherwise). Huge company that's essentially run by the lawyers and bureaucrats. Very hard to make a decision, and hard to make one stick. False "consensus" culture that's really about doing what higher managers decide. People afraid to make decisions. Older profitable (and user-loved) desktop software almost entirely moved to India now (with very little improvements scheduled), with talented US engineers shuffling between new mobile/tablet projects that get killed off quickly. Company still identified with the older creative products, but there's little or no investment in those: it's all about the new marketing acquisitions.
