What do git add and git commit do?
PICTURE THIS: STACK VS QUEUE
Simple meaning
git add stages chosen files so they become part of the next snapshot.
WHY — Git instead of guessing?
Why interviewers care about Git:
who only read docs from people who shipped.
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:
- 1git add stages chosen
files so they become part of the next snapshot.
- 2git commit records that
staged snapshot with a message on the current branch.
- 3Interviewers expect you to
stage related changes only and write messages that explain why the change exists.
- 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.
EXAMPLE — See it in action
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
git add stages chosen files so they become part of the next snapshot. git commit records that staged snapshot with a message on the current branch.
