American Express

• Truly attempts to uphold what Amex calls "Blue Box Values." Not just lip service.

• With recent transformations, especially using the technology-first approach, the company has molted from its state in the first decade of the millennium.

• Like with any very large global corporation, you cannot expect the agility of a startup, but the company places very high value on agility and speed of decision-making.

• You are treated as a person, not just a body with a brain and hands.

• Senior management takes employee feedback seriously.

• Very large, matrixed, global, multinational corporation. This makes it a challenge to get a grasp on the who's-who in the company.

• Being a bank-holding company, technology decision-making does get impeded due to strict government regulations around the finance sector.

Keep up the good work. Focus on completing the transformation at all levels of organizational hierarchy that was started earlier this decade and has worked wonders thus far in preparing the company for what lies ahead.
