It's not like you push anything important your first day. You spend two hours doing some simple bug fix that would usually take you 15 min and then spend the next six hours learning how the CI and deployment pipeline works, usually with someone holding your hand.
CI and deployment pipeline?!? What are you a spoiled millenials thinking... we build local, and copy the whole folder over RDP copy/paste onto the production server.
You may laugh, but I've seen that far more often than an actual CI/CD process in place...
