How was the code review process carried out in your previous company before merging or deploying code?

In my previous company, the code review process before merging included several stages:

1. Pull Request (PR) — the developer creates a PR in the version control system (e.g., GitHub or GitLab).
2. Code review — colleagues review the changes, leave comments, and suggest improvements.
3. Automated checks — CI/CD pipelines are run, which perform build, tests, and static code analysis.
4. Approval — after all checks are successfully passed and comments are addressed, the PR is approved and merged into the main branch.

This process helps maintain code quality and reduce the number of errors in releases.
