Pros
The CEO is an amazing leader as well as many of the people holding senior management positions. They are incredibly intelligent yet humble. Diversity is absolutely embraced and the right person for the job is hired regardless of gender, culture, age etc. The culture is polite and everyone treats each other with respect. The employees are very sharp and know all aspects of the payments industry. The company embraces innovation and is a leader in emerging payment models.
Cons
The company is very top heavy with too many people in middle management who really aren't working. This promotes a country club like atmosphere. There is a huge gap between the senior management team and the people who actually get the work done. It's the business leaders that do all the work without reward or recognition. If you want the easiest job in your life and get paid a lot for doing nothing go for a middle management position at MasterCard.
