Stop Guessing.
Start Negotiating.
The definitive guide to cracking the SDET interview. Master the strategies and frameworks you need to go from manual tester to Senior SDET at top-tier companies.
The "Black Box" Interview
Tired of failing interviews without knowing why? You leave feeling like you did well, but never get the callback.
The Coding Wall
Struggling to solve LeetCode style problems under pressure? You know the syntax, but the logic escapes you when the clock is ticking.
The Senior Gap
Stuck in manual testing and can't bridge the gap to automation? You want the senior SDET salary, but can't break out of execution mode.
There is a better way.
It’s not about memorizing answers.
It’s about having a Playbook.
The 3-Pillar Framework for Success
Passing the interview isn't just about code. It requires a holistic approach. Our system is built on these three non-negotiable pillars.
1. Strategy
The STAR Method
Master the art of behavioral interviews. Learn to tell compelling stories that highlight your leadership, conflict resolution, and culture fit.
2. Technical
The U-PER Framework
Stop memorizing solutions. Learn a systematic framework (Understand, Plan, Execute, Review) to deconstruct and solve any coding challenge.
3. System Design
Scalable Test Architecture
Move beyond writing scripts. Learn to architect robust, scalable test automation frameworks that can handle enterprise-level complexity.
The Industry Standard
Desk Reference.
Available in Paperback and Kindle. This isn't just a book you read once; it's a 200+ page battle-tested manual you'll keep on your desk for your entire career. Packed with no-fluff strategies and frameworks.
Is This Right For You?
This playbook wasn't written for everyone. It was written for ambitious engineers ready to level up.
The Transitioner
You're tired of repetitive manual testing. You know code is the future, but you need a structured path to build frameworks and write scripts that work.
The Climber
You're already coding, but you want to break into top-tier tech. You need to master system design, architecture, and the leadership soft skills to get the promotion.
The Graduate
You have the theory, but the interview process feels like a black box. Skip years of trial and error with a roadmap designed to get you hired fast.
Meet the Author
Hien Nguyen
For over 20 years, I've been building and leading world-class Quality Engineering teams in Silicon Valley.
I've sat on the other side of the table for hundreds of interviews. I've seen brilliant engineers get rejected not because of their technical skills, but because they didn't have the right strategy.
I wrote The SDET Playbook to change that. My mission is to give you the insider's map—the exact frameworks, mindsets, and technical strategies you need to stop guessing and start getting offers.
