How did you perform code review at your previous company?

In the previous company, code review was conducted through a version control system (Git) using pull requests (PR). Each developer created a PR, after which colleagues conducted a review, checking code compliance with standards, readability, logic, and potential errors. Automated static analysis tools such as clang-tidy and cppcheck were also used to identify issues early on. An important part was integration with CI/CD, where unit tests and project builds were run, allowing errors to be detected before merging code into the main branch.
