Disclosure

StackChief is free to read. It's funded by display ads, by digital products sold here (such as the AI Engineer Interview Kit), and by sales of my book. This page explains how that works so you can weigh my recommendations accordingly.

Ads and products

Some pages show Google ads. I don't choose the individual ads, and advertisers don't influence what I write. When an article mentions a StackChief product, it's one I sell and earn from directly.

AI assistance

Since October 2026, new articles are researched and drafted with AI tools that I direct, and every figure is checked against its primary source before publishing. I'm responsible for everything published here.

I wrote the book I recommend

Mastering the Tech Interview is written by me, Sam Erickson, and published by StackChief. When you buy it, I earn a royalty. That's why it appears on this site.

What doesn't change

Articles are written to be useful on their own. The book is mentioned where it's relevant, and the site never shows Amazon prices or ratings, because I can't keep those accurate. Check Amazon for the current details.
