Why interviewers care about asyncio:

This is a process

question about asyncio.

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.

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

1

3

4

synchronous unless you use the async interface.
5
Common mistake
What juniors usually get wrong.
6

When you pick this over the alternative.
