Would you like a flowchart-based guide to systematically establish the foundations you need for rock-solid confidence in high-pressure whiteboard interviews at big tech companies? That's what we offer. Today, my coauthor and I are both highly-paid employees at Big Tech companies. Previously, we both failed multiple "big tech" interview processes then succeeded. And now we wrote a simple book to teach people a systematic step-by-step process to succeed. Here's the TL;DR, but you can actually see the diagrams with the "Look Inside" Learn to implement data structures from scratch. This builds the intuition you need to learn the algorithms from scratch. Those fundamentals are what you need to conquer the medium Leetcode problems in order to make the big tech salaries. Confidence under pressure comes from competence. We don't promise an easy journey – we both solved about 100 medium Leetcodes – but we promise that having the proper foundations makes the journey natural, rewarding, and improves your skills as a programmer. We both felt overwhelmed by the huge books and expensive courses on the market, and even after buying these, didn't get through them – we said "screw it". After all, we're both passionate programmers, have worked at many startups, and have tons of industry experience (only one of us has a CS degree). What we did was conquer the path into great jobs at great companies and we want to pave the way for others. As such, we are seeking "early readers" to provide brutal feedback on an early draft of our book. This is in early release edition, so it's priced low, and we need people to provide brutal feedback. If you purchase this edition, you will receive future updates for free until we make a general release edition. Early feedback has informed us that this is a simple, easy-to-read book – it's a manual, and it's intended to be as readable as a GETTINGSTARTED.md guide of an easy-breezy open source project. Ever get confused about something in the book, just email us (sesurvivalguide@gmail.com) and we will coach you (and rewrite the text) until it's easy to understand.
