[Google — 5 months ago](https://www.aced.io/experiences/google-staff-software-engineer-interview-7c56ac) — Software Engineer, Staff / L6. “Technical Depth: The technical discussions felt like peer-to-peer architecture reviews rather than a standard quiz. Mission Alignment: Every interviewer was deeply aligned with the company’s core focus on safety, reliability, and scaling responsibly. Problem Scope: The system design scenarios perfectly mirrored the actual, massive-scale infrastructure problems the team faces daily.” 2. [Google — 7 months ago](https://www.aced.io/experiences/google-software-engineer-interview-a24efe) — Software Engineer, Mid Level / L4. “The process was pretty straight forward.
