All software companies must take an intentional and structured approach to code reviews. There is no "one-size-fits-all" approach for code reviews; it varies depending on the codebase, the company's size, and the team's preferences. When a company is starting out, code reviews should look different than during rapid growth, or product maturity. As a company grows, more people should be performing code reviews as more people perform reviews. A major goal of code reviews is as a teaching tool for junior engineers.
