Hien Nguyen is a software quality professional with over 20 years of industry experience, currently driving engineering excellence at Google. He is the author of The SDET Playbook: From Recruiter Screen to Final Offer, a definitive guide dedicated to helping engineers master the complex landscape of technical interviews.

Throughout his career, Hien has designed, built, and consulted on scalable test automation frameworks and backend quality solutions using modern technologies like Python, Java, Next.js, and PostgreSQL. After successfully navigating highly competitive interview processes at top-tier tech companies, he recognized a critical gap: brilliant engineers often understand the technology but lack a coherent strategy for the high-stakes interview loop.

To bridge this gap, Hien founded The SDET Playbook communities across YouTube, LinkedIn, and Reddit. His mission is to empower QA professionals, Test Engineers, and SDETs with the exact frameworks, technical insights, and communication strategies needed to confidently navigate the hiring gauntlet and secure their dream roles.
