You have gotten the scholarship already. Just await the award letter so you can start the visa application process. I am at the same stage too but different schools.
The link to the Daad portal will be given to you by your school if you are awarded the scholarship. ( This response is for the Epos category only. I don't know about the other scholarship categories)
Congratulations @Isaramirezca. I have been stalking your posts for a while now. It feels like a decade since i had my interviews.
DAAD EPOS -PPRE, Oldenburg. Anyone in my boat?. I am literally done refreshing my mailbox
