THE MOMENT IT STARTS TO CLICK.
From getting unstuck to taking the next career step. Here’s how students describe their experience.
Read more student storiesAfter going through all the lessons, I gained the necessary skills to perform well at my on-sites. I crushed even the DP problems, which were my biggest fear. And thanks to that I landed offers from Microsoft and Uber. Thank you AlgoCademy!

AlgoCademy really helped me improve my problem solving skills and write incredibly clean code. I was worried it wouldn’t be done in time for my coding interviews, but the way the curriculum is structured made me progress very quickly. Thanks for your work!

Wow. I've been using AlgoCademy for a while and now I can finally solve coding questions on my own. This gave me the confidence I needed for my interviews, and guess what? I landed the offer at Samsung! You guys truly kick ass. High fives!

A FEW QUESTIONS BEFORE YOU START.
So, you have questions? Let us try to answer those for you...

Yes! The content is designed to cover everything you might encounter in coding interviews. We start with simple loops and statements and move to famous algorithms and data structures, as well as how they apply to the interview questions these companies ask. Our graduates tell us how many of our questions get asked by companies all the time!
Beginners welcome! While we do assume a very basic general understanding of how computers store variables and loops, you don’t have to worry about anything else. You’ll learn the rest here. It’s also going to be easier than you think! The original inspiration for AlgoCademy came from helping a friend who quit his job as a singer to follow his dream. We’ve always had beginners and self-taught programmers in mind (as well as CS majors) while building our content. We can meet you on your level and take you from there!
No drip-feeding here! You get access to everything inside AlgoCademy right away. Jump in and start making use of the training without having to wait for something to be released to you. We also regularly update and add new material, so your content library will continue to grow alongside your knowledge.
You do not need to know any specific language to benefit from our lessons. Our explanations focus mostly on core intuition and pseudocode so that every coder out there, no matter the language, will understand everything.
Every day you hold off on membership is another day you’re not working toward your dream job. It’s time for you to take action. We provide the answers to all of your questions, including the ones you don’t know you have yet, that will pave the way to a high-paying programming job. Becoming a member will help you find the support, community, and most importantly, accountability necessary to reach your goals. AlgoCademy is the place where you can find all of these things. If you are ready to make a difference in your life, the time is now. Simple as that.
The average base salary of a software engineer is $110,464, according to Indeed, and the average total compensation for FAANG companies is over $250k, according to levels.fyi. The better you perform in your interview, the more desirable you become, therefore giving you the power to negotiate compensation. You’ll also get to work at your dream job every day alongside top-tier software engineers. It’s hard to put a number on all of that, but we think it’s worth it.
