@OP consider your needs. If you are truly as desperate as you say, apply for the job. However, it only takes a few scrolls on this page to fully understand what this organization values and it will never be you or your well being. They will work you into the dirt, they'll have layoffs and "distribute the work" and spin it as an "opportunity to do more within the company" with no pay increase. Once review time shows up you'll be disappointed that you only got a "meets expectations" and when you advocate for yourself they'll make up an excuse saying that higher ups need to approve it but the managers will never fight for their teams and team's advancement. In truth, I was in the same position when I came to Fiserv. Everything started out okay, but then came the Sapience computer/click tracking, the unrealistic expectations, the cracks really began to show. Thankfully found something better and found out a month after my departure that my director got axed, entire team is being restructured, and now the VP of my old dept is stepping away to manage another team.
In my time at Fiserv I've only known people to work there out of necessity. Honestly I can't think of a single person that genuinely enjoys working at that place or has anything good to say...unless you're a C-Suite exec that is.
Best of luck OP...
