Were code reviews conducted by colleagues in your previous company, and how often did this happen?

In the previous company, code reviews were conducted regularly, usually before merging changes into the main branch. The frequency depended on the project, but on average, it happened several times a week. Code reviews helped improve code quality, identify errors, and share knowledge within the team. Tools like Gerrit or built-in version control system features (GitHub, GitLab) were typically used. Such a process contributed to maintaining standards and training newcomers.
