Would you like to not suck at interviews? Disappointed all your friends work at FANG (and you don't)? This is not a nice book, but it is a helpful one. Interviews are their own special flavor of weird - I should know, I've spent fifteen years giving and surviving them, and this book will teach you how to get past them, with a modicum of your sanity intact.
No fancy models, systems, or memory drills, this book will help get you into your favourite tech company, now. It's anonymous because I like my salary more than I like being a 'highly paid author'. Interviews have changed during COVID - what was in-person is now almost always a video call. That comes with it's own challenges and techniques.
... just read it. Worst case, you learn something! Best case, it helps you get the job.
