Steve Huynh spent 17 years as a Principal Engineer at Amazon, conducted nearly 1,000 interviews, and ran approximately 600 as a Bar Raiser. That last role is Amazon-specific: an interviewer from outside the hiring team whose sole job is to protect the talent bar. After leaving Amazon, Huynh spent 2 years writing 'Technical Behavioral Interview: An Insider's Guide', and The Pragmatic Engineer published both his observations and a 75% excerpt from one of the book's 14 chapters.
The core argument is blunt: technical interviews are mutating fast under AI pressure, but behavioral interviews are not changing, and most engineers are underprepared for them. At mid-sized and large companies, a strong technical performance does not save you if the behavioral round flags a culture or fit problem. The offer, and the level you land at, both depend on how you perform in a format most engineers treat as secondary.
The full piece is worth reading for two specific sections. First, Huynh's direct observations from 1,000 interviews, including how story delivery is weighted against story content, and why the behavioral round functions as an audition for day-to-day collaboration. Second, the book excerpt details the four dimensions companies use to calibrate your level, how to read your own level accurately, and how to research what a specific company actually values before you walk in.
