Google's senior backend engineer interview process is a multi-stage evaluation designed to assess algorithmic problem-solving, system design expertise, scalability thinking, and cultural fit. The process typically consists of an initial recruiter screening, two technical phone screens focusing on coding and system design, followed by 4-5 onsite interview rounds that test coding proficiency, advanced system design capabilities, architecture thinking, and behavioral alignment with Google's values. For senior-level candidates, system design and complex infrastructure challenges are weighted heavily.
