Pros
First, the current 5 star reviews are highly suspect. I'll put money on it being the work of corporate shills. You can sense the low morale just strolling the hallways. Great people but they are leaving in droves. They will pay you but the lowest amount possible. Good if you are desperate for work. That's it.
Cons
Benefits are not competitive to industry standards. Expensive health insurance. Pay is on the low end. Raises and merit increases are just laughable. Poor stock options. Even poorer 401k. No matching. Hemorrhaging their best talent. Knowledgeable employees are leaving fast. Absolutely no work from home. The CEO even has the time to even review employee card scan history. Think about that. Who honestly has the time to worry about something so trivial? Key stoke and time tracking software installed on computers. Corporate loves to say they are all inclusive to LGBTQ community but the CEO donates over 100k to Trump and the Republican party. I'm sorry but that's just contradictory. It's public record, look it up. Corporate also loves to tout about their diversity. Go take a look at the people in the offices for directors and above. Very poor covid response. One of the last big companies to allow work from home and one of the first large companies to force a mandatory 5 days in the office. Even with the delta variant surging. Strong armed long term work from home employees to return to the office or resign. All during the pandemic. Absolutely abhorrent behavior from a CEO. The wonderful culture that Fiserv had is long gone . There is no hope. The toxic culture is trickling down from the executive suite. Honestly, please just look at the negative reviews. They are all spot on and truthful. I wish I was kidding. Run away from this place and don't ever look back. It's truly a sinking ship.
