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.
