Fiserv from a stable employees point of view
Pros
General environment is good, there is no pressure related to dress code or in/out timings (which I believe people at times misuse). Management does listen to employee feedback though at times it takes time to implement certain changes and at times they listen but they don't - probably because of cost pressures or because employees ask them to be "too" fair (too here is rhetoric because there cannot be a degree of fairness - you are fair or you are not)
Cons
Over all the company is not bad but it is no more that good as it used to be about 5-6 years ago. Probably the cost cutting pressure has caused the management to behave a little irrationally but I think that's the trend in Indian IT industry!!! IT policies have imposed way too many restrictions causing lots of trouble to employees so many times. And the IT support staff doesn't look really professionally competent. Again probably the result of cost cutting measures.
