Pros
Gorgeous facility, meaningful mission. Some of the best people working there. Good education opportunities.
Cons
It's a pretty monster on the outside but it's got huge, sharp teeth. The organization leadership takes on too much without successfully implementing what they already have on their over-flowing agenda meaning everyone is frazzled all the time. Tremendous churn in key leadership in recent years which does not bode well. Meetings are piled up three and four deep on one another. PMO is treated as a joke and worked around instead of with. IT burnout is high for a reason. All the gourmet cafeteria food and profit sharing in the world doesn't make up for the fact you will be expected to work in a chaotic environment with a never ending stream of huge initiatives because upper management can't say no to anything.
