Pros
They are desperate for bodies, so if you are having trouble finding work it might be a good place to start before you move somewhere else that cares about its employees.
Cons
Fiserv under its current management cares about nothing more than tax cuts and tax incentives. They have been obsessed with moving positions (not people -- they don't seem to care that they are losing droves of knowledgeable people) to certain locations where they get tax incentives. The decision making in this company has been extremely erratic since Frank Bisignano took over as CEO. For example, there was a two week period where the work from home policy changed THREE times. Even worse, people will get notified that their site is safe for the foreseeable future only for that decision to be reversed months later. This company is not reliable and does not care about its employees. This company says that it cares about its clients, but the metrics that they track for Support have nothing to do with customer satisfaction. Instead all that is looked at is how many days you are in the office and how many hours of "work" you track on the company's PC spying software. If you have any other options at all, take that before you take a position at Fiserv. Their decision making is too erratic and they do not keep their word.
