Pros
If you are a person who lives for good benefits and job security, this company is for you. If you pride yourself as innovative and an independent thinker, run as far as you can.
Cons
American Express is a private club, not only for its card members, but for its employees. It is a mutual admiration society, and on most days, resembles an incestuous clique. If you are part of the right team, and should be lucky to find a good leader, then all is well. If you find yourself on a team where you don't fit in, you will suffer a lot, as it is a consensus culture where your ideas will not be respected unless ALL members of your team agrees. The by-product of this culture is SUPER SLOW BUSINESS SPEED and total LACK OF INNOVATION. They always promote from within, so its the same people in 12 different roles and titles. Same boring ideas, same pat on the back for mediocre group think. Leaders are generally poor quality, even though they are forced to go through this Harvard leadership certificate program (most don't even show up to class or do their work but get the certificate anyway). There are few opportunities to move up as everyone stays around forever because of the benefits.
