Give effective code reviews: feedback, mentorship, knowledge sharing. Catch bugs, improve code quality, grow engineers. Essential senior+ skill. Code review is the collaborative practice of examining code changes (usually via pull requests) before they merge into main. Reviewers spot defects, suggest improvements, share knowledge, and enforce team standards. In 2026, code review is the primary mechanism for knowledge transfer, junior engineer onboarding, and quality control. Great code reviews catch 50%+ of bugs before production, transfer domain knowledge across the team, and build psychological safety (people learn faster in non-judgmental reviews). Bad code reviews become bottlenecks (slow turnaround time kills velocity) or breeding grounds for resentment (nitpicky tone kills trust).
