Fit on train, tune on val, report on test once.

Simple meaning

Throttle classes implement allow_request and wait, typically using a cache key of user id or IP plus a rate such as 100/hour.

WHY — DRF instead of guessing?

Why interviewers care about DRF:

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.

Stay structured

Name the idea, why it exists, then one short example.

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
Throttle classes implement allow_request
and wait, typically using a cache key of user id or IP plus a rate such as 100/hour.
2
ScopedRateThrottle lets different views
share or split budgets.
3
Because it is cache-based,
a dummy cache in tests disables throttling unless you configure one.
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.
