Google Senior Site Reliability Engineer Interview Preparation Guide

Google's Senior SRE interview process typically consists of 7 rounds spanning 4-6 weeks. The process begins with a recruiter screening, followed by two technical phone screens assessing coding and systems knowledge, and concludes with four onsite interviews covering coding, system design, Linux/troubleshooting expertise, and behavioral/cultural fit. Google evaluates candidates on four main attributes: General Cognitive Ability (GCA), Role-Related Knowledge and Experience (RRKE), Coding proficiency, and Googleyness & Leadership. The interview emphasizes problem-solving in ambiguous situations, systems thinking, and the ability to design scalable, reliable infrastructure.
