Hah, that takes me back!! MY first internship was at SAP and I foolishly didn't even ask which technologies I would work with... ABAP is literally the worst lol. This was 2018 btw
At SAP, you get to use all the latest features and are free to change basically anything. On the customer/consulting side, we get to work around terrible ancient standard implementations and our products need to work on old systems, so 700 syntax it is.
And don't get me started on forms.
