The company benefits and the caliber of people that I worked with was outstanding. I was happy there and still keep close contact with the coworkers I supported. Lack of funding was the only reason I left.
As in all places these days, raises and bonuses seem to be few and far between, even with an "all in" work ethic. As a publically traded company, our investors were made happy at the cost of raises and bonuses. I was close to the sales organization so knew the lofty sales goals were being met, but told that there was no money to adjust my salary to even where my coworkers were compensated. (I worked there for almost a decade so my salary had not increased to be commensurate with my role.)
If you are willing to put in the work and are looking for a great work environment, I do recommend employment at FIS. Starting pay and benefits are good, but look to move to another company 3-5 years down the road to advance your career.
