Why does Python need type annotations if it's a dynamic language? Are they checked when the program runs?

~4 min by voice

How to approach it

They're checking whether you understand that type annotations in Python are metadata for people and tools, not a runtime check. They also look at whether you know who actually uses them and how: mypy/pyright, the IDE, Pydantic/FastAPI.
