BSC Global interview questions

I've been interviewed for 3 times , 3 technical rounds and they said that one last round is still pending, hope to crack it well , and join them as a SAP ABAP Developer

The HR round was very short, around 3 minutes. I was only asked for my self-introduction and salary expectation. I was told to be ready for a technical interview the next day, but no timing or details were shared. I tried messaging for clarification but didn’t get any reply. (Better communication and clear scheduling would really help candidates.)
