In my opinion, interior walls must be installed before screed because you are screeding the rooms (with insulating strips around the edges; edge insulating strips). Otherwise, the wall would have to be put on top of the screed, which would not be professional at all (soundproofing, expansion behavior of heated screed, stress, etc.).

In interior drywall finishing, the wall is often installed and sheathed on one side. On the other side, only one (half) board is attached from below. The screed can then be laid, but the wall is left open so that further installation work can be done later.
