Pros
Free coffee. Job security due to turnover. They can't afford to fire anyone. Get hired right away.
Cons
Management is too far removed from the workers. Managers are managing products they don't know anything about. Departments are run with different company policies although the motto is One Fiserv. The company response to negative feedback is if the employee no longer works at Fiserv then their reasons for leaving are not taken into consideration as an opportunity to better the work environment. Fiserv sent out their own internal survey and they never revealed the results, rather sent it to the employees manager who confronted the employees about their negative feedback. Stay far away from this company unless you are in desperate need of money. They have a lot of jobs that are really slack and serve well as a job filler but will not lead to a career.
