This is a process

question about DRF.

Panels listen for order,

trade-offs, and what you would actually do on a Python project - not buzzwords.

Close cleanly

End with when you use it and one common pitfall.

STEPS — What happens step by step?

Before you speak the answer, walk the interviewer through these steps:

1
GenericAPIView plus mixins gives
you get/post handlers and queryset/serializer_class.
2
A ViewSet maps actions
such as list, retrieve, create to HTTP via a router instead of one method per verb.
3
Routers then generate URL
patterns from the viewset, which is why DRF APIs stay compact.
4
Give an example
One tiny concrete case you can say aloud.
5
Common mistake
What juniors usually get wrong.
6
Close
When you pick this over the alternative.
