Download and solve practice problems in over 30 different languages. Submit the solution to the site for feedback (beta). For code newbies and experienced programmers. Learning to program is exhilarating and challenging… and also frustrating, exhausting, and overwhelming. Exercism provides countless small wins. The exercises are achievable mini-quests: small and well-defined, and with enough complexity to uncover bite-sized knowledge gaps. The solutions you write provide reviewers with clues about what you haven’t grasped yet. The feedback you receive will guide you to relevant study topics and dramatically increase the ease with which you write code.

Tutorials and Education



CareerCup’s founding was more accidental than anything else. Back in 2005, when Gayle Laakmann McDowell was graduating college, a friend two years younger asked her to keep some notes on where she was interviewing and what she thought of each company. Gayle did that, but also decided to record all the interview questions (which you can still see). Word got out about this list of interview questions, and pretty soon it became faster to post it online than to email around a Word doc. (After all, engineers are all about efficiency!) Then people discovered this page (which was, at that time, just hosted off her personal website) and traffic grew. And then other people started to contribute their questions. Slowly, bit by bit, it evolved into the CareerCup we know and love.

Teach Yourself Computer Science


If you’re a self-taught engineer or bootcamp grad, you owe it to yourself to learn computer science. Thankfully, you can give yourself a world-class CS education without investing years and a small fortune in a degree program 💸. Study nine subject areas using either the suggested textbook or video lecture series, but ideally both. Aim for 100-200 hours of study of each topic, then revist favorites throughout your career 🚀.

Hacking a Google Interview


Learn the tricks. Beat the system. Ever wanted to work at a company like Google, Apple, or Facebook? There’s just one thing standing in your way: the interview. But there’s no need to fear. We’ve mastered the interview questions and topics, and we want to show you how you can nail every programming question. Whether you’re a beginning programmer or a seasoned expert, this class is for you. The class focuses on computer science topics that frequently come up in programming interviews. It covers time complexity, hash tables, binary search trees, and some other things you might learn in 6.046. However, most of the time is devoted to topics you won’t learn in class, such as crafty bitwise logic and tricks to solving problems. If you have any interest in working at a computer science company, make sure you don’t miss this class!

Rosetta Code is a programming chrestomathy site. The idea is to present solutions to the same task in as many different languages as possible, to demonstrate how languages are similar and different, and to aid a person with a grounding in one approach to a problem in learning another. Rosetta Code currently has 869 tasks, 207 draft tasks, and is aware of 677 languages, though we do not (and cannot) have solutions to every task in every language.

Interview Cake


This is not a freaking textbook. No confusing academic jargon. No long lists of properties to memorize. No proofs. Because that stuff doesn’t help you actually get it. Here’s what does: Learning what to picture in your head when you think of a dynamic array or a hash map. Learning how to think in algorithms. That’s what this guide is focused on—giving you a visual, intuitive sense for how data structures and algorithms actually work. So if you’ve got a big coding interview coming up, or you never learned data structures and algorithms in school, or you did but you’re kinda hazy on how some of this stuff fits together… This guide will fill in the gaps in your knowledge and make you say, “Oooh, that’s how that works.” We’ll walk you through it all, step by step. Starting from the beginning.
