Pros
Lots of smart people. Rational decision-making (mostly). Good WLB, best office environment hands-down, and unusual perks like free food and a fully paid-for weekend in the White Mountains with your loved ones. Culture of continuous improvement and feedback that really helps you get your work products to the next level.
Cons
Rigid processes, and clinging to long-held beliefs, like you can stick with a rigid software license model and still compete with open source, onerous approvals that prevent innovations and slow down progress, still using a rigid waterfall development process with 2 releases per year and no ability to change plans with less than a year delay. Managers who just "talk the talk" of supporting you, but don't walk the walk, and don't hesitate to shoot down your own ideas while dinging you on not making enough impact. Inability to move anything quickly - your customers wait at least 1.5 years to see gaps closed or new features to respond to their requests or market trends, new content typically takes 6 months to be developed, revised, approved and pushed out, etc etc
