Explain the difference between origin and upstream.

Short answer: origin – The main remote repository you cloned or own. upstream – Usually refers to the original repository that your fork came from.

Example code

If you fork a popular open-source project: Your fork on GitHub = origin The original repo (the one you forked from) = upstream Commands to set both: git remote add origin git remote add upstream Why it matters: This setup lets you pull new changes from the main project (upstream) while pushing your changes to your fork (origin).

Real-world example (ShopNest)

ShopNest’s team uses GitHub PRs with reviews and CI checks so broken builds never reach production unnoticed.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
