Simple meaning

async def defines a coroutine function.

WHY — asyncio instead of guessing?

Why interviewers care about asyncio:

asyncio 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.

STEPS — What happens step by step?

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

  1. 1
    async def defines a

    coroutine function.

  2. 2
    Calling it returns a

    coroutine object

  3. 3
    it does not run

    until you await it or schedule it on the loop.

  4. 4
    Mixing blocking ORM calls

    inside async def without sync_to_async will stall the loop.

  5. 5
    Common mistake

    What juniors usually get wrong.

  6. 6
    Close

    When you pick this over the alternative.
