3 Interview Questions with STAR Answers
Tell me about a time you raised the bar on a process or team (Insist on the Highest Standards).
Our team's code review process was inconsistent — some reviews were thorough, others were rubber-stamped.
I was asked to improve code quality across the team.
I created a code review checklist with specific criteria, implemented automated linting rules, and established a 'no merge without two approvals' policy. I also ran weekly code review workshops.
Production bugs dropped by 60% over 3 months. The checklist was adopted by 3 other teams, and I was asked to present the process at our engineering all-hands.
