Pros
They pay well, and have a lot of add-ons that add up (bonuses, company shares, employee rates for uying share, company contribution to 401k) Life-work balance is one of the best. You start with 25 vacation days. They don't fire people - most of the times, if need be, people are reallocated to other areas. They make an effort to make the work environment more fun: on-site gym, entertaining area (games, Wii, ping-pong table), etc. New (2014) program for more flexible hours
Cons
People become too comfortable, life too sweet makes working with certain areas very difficult and slow. Many jobs overlap and add redundancy. Highly regulated environment, and corporate culture make decision-making a difficult and painful process. Like a lot of the financial institutions, technology is not given enough importance. New technologies are implemented when there is no other way. Again another painful, long process.
