Had 6 rounds of interviews, told all was going great along the way, then I was ghosted for weeks after my final interview. Chased HR three times but no reply. I found out I didn't get the job via the FIS portal and got zero feedback after spending so much time prepping and interviewing for weeks. I was eventually contacted by HR who said they were very confused I didn't get the role and that someone else was chosen. The next day the role was relisted and is still active.
Horrible process through out and it's a real indication of what it would be like to work for FIS so I'm glad I didnt work with them in the end.
