Pros
Fiserv has great benefits- insurance plan is the best that I have seen in an employer. They also promote Weight Watchers and have some fun competitions to keep you physically active. The people in Sioux Falls, SD are a good group and will always help you when needed.
Cons
Training "program" is horrible for new employess. It was basically like you start and figure things out for yourself as you go along. There wasn't ANY formal training in my position which makes it a little scary considering you have to present yourself to banks who have purchased Fiserv products. Things are constantly changing, which is expected when working with software and technology but it's almost like you never get an opportunity to fully grasp the software before it changes. They try to promote "one Fiserv" but it's nearly impossible. There are times I will have to speak with 5 different people before finding someone who knows the answer.
