Before you decide to sign on the dotted line, verify that what you have been promised in terms of potential, software and other development practices, engineering teams and expertise actually exist because when I worked there, it didn't and I've seen job specs recently out in the market (April 2021) that are um.... fictional. To say the least. I've seen references in recent ads to 'event driven architecture', 'microservices', software development. That expertise does not exist at FIS currently (April 2021).
When I joined, the interview process was rushed and it's only with hindsight that I realised the purpose of that: bait and switch. The person interviewing me did not turn out to be my line manager in the end, despite it being claimed at the time. My boss was someone else entirely who started at the same time as I. That person I would not have chosen to work for because of his poor skill set. Bait and switch happens for a reason.
I experienced very poor life/work balance because based in the UK, I had to support both the UK and the US. On my own. 12 hours days were common and I worked weekends sometimes. On top of that, the senior director constantly bugged me on Slack. I had to do some of my line manager's work because he lost his nerve around anything complicated. A very stressful work environment that over promises in terms of reward and under delivers.
A lot of staff, including contractors, left early 2021 and I believe they are trying to build up capabilities now. Do not believe for one second that much of what is advertised already exists. If "hands on" is mentioned in the job ad, expect much of your time spent on Jenkins / GitHub / troubleshooting something that's been broken for months.
