Simple meaning
Celery is a distributed task queue.
WHY — Celery instead of guessing?
Why interviewers care about Celery:
Celery questions separate people
who only read docs from people who shipped.
Keep it short, concrete,
and tied to Python work.
Stay structured
Name the idea, why it exists, then one short example.
Close cleanly
End with when you use it and one common pitfall.

image processing, and anything that should not block the request.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.
