PICTURE THIS: GIT FLOW
Simple meaning
Require passing CI, at least one review, and up-to-date branches so green checks match the latest commit.
WHY — CI/CD instead of guessing?
Why interviewers care about CI/CD:

and tied to Full Stack work.
Name the idea, why it exists, then one short example.
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:
- 1Require passing CI, at
least one review, and up-to-date branches so green checks match the latest commit.
- 2Why it exists
Block force-pushes on main.
- 3Optional owners for auth
and infra paths keep risky files from merging unnoticed.
- 4Give an example
One tiny concrete case you can say aloud.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.

Here's a short line you can speak, broken into clear beats:
Note: Adapt this scaffold to your own project — keep it under 60–90 seconds.
Key takeaway
Require passing CI, at least one review, and up-to-date branches so green checks match the latest commit. Block force-pushes on main.
