What’s the process for when it rains on new build houses/apartments before the roofs go on? Do they just let it dry out, no mold concerns?

I’ve seen them paper the plywood the day after rain. Not saying it is the right thing to do but generally the walls are still not finished with drywall on the inside or siding/stucco on the outside so there is still lots of airflow in the roof.
Tract homes are what they are.
As a general rule of thumb you’re not really going to be installing anything that will get damaged by rain before you put the roof on.
So for most things yeah – you just let it get wet and then dry out when it stops raining.
Mold and such shouldn’t be a concern because there shouldn’t be any building materials being used at that stage that would be prone to mold. Plus there’s still plenty of airflow, etc at that stage of a build so once it stops raining stuff should dry out fairly quickly.
If it’s going to rain for an extended period of time that you’re probably going to want to cover stuff with tarps to prevent too much water building up
I spray fireproofing on the structural steel of new buildings for a living. There is extra money in the cost of the project for us to repair water damage.
We were on vacation when our roof was replaced. Every day I saw torrential storms on radar. We chased waterspots on the ceiling for quite a while.
After the roof goes on, and the sides are covered in plywood, then vapor barrier the windows are still open to allow the inside to dry
