Pros
Its a job. So many still out of work. There are some really hard working people here.
Cons
This is not the place to build a technical career. Only management are allowed to have ideas that are acted on. This is because they are intimidated and fear being out-shined by their employees. What an unhealthy culture. While Google and Apple are about growth and innovation, Fiserv is about keeping the status quo. All change is bad all the time. Dont expect any training that will keep your skills relevant. No matter how many hours you routinely work or how profoundly you improve a process or practice you will NEVER be seen as anything but "average". You are not allowed to excel here because then they would have to reciprocate you for that. That is something that they dont do. Its pretty clear that the "good" reviews on this site are seeded by management or one of the PR efforts to counter the truth. A better investment would be to reboot the culture. Emulate one that works on all cylinders.
