Pros
Huge company with all the benefits that go along with that. Lots of (potential) opportunity within the company.
Kontras
Budget micro-managed to the penny. Very strict travel policies and restrictions. Huge company, but very unknown throughout industry because of their lack of branding (change in 2009). Management doesn't understand the companies/products that have been acquired over the years. Everything treated as a "widget", independent of synergies and cross-selling opportunities with other Fiserv products. Systematically make everyone into a drone, and irritate clients with penny-pinching ways. Management sees the products as leaders in the industry - some are, but many are not. They need to understand where each product is positioned.
