Explore the Most Common
Interview Patterns
Use AlgoMonster to learn the patterns. The internet has no short supply of problems, however like an unsolved
puzzle it can be a daunting task to see the big picture and patterns. Luckily interviews are centered around a small set of
patterns. These are repeated over and over. Learn these building blocks, you'll be able to apply them to any problem.

AlgoMonster learners have inspiring stories to tell
“I am 42 years old and I hadn't touched the subject of algorithms and data structures since college time, when I had learned it in a very limited way. For more than 1 year, I tried to study on my own without a guidance, and I regret all the precious time I lost in this journey, as it was completely unproductive. Then, I found AlgoMonster. Using the guidance provided on the website, I felt the time I reserved for studying was being completely better applied, and in 1 month I had advanced more than I had in one year. After a while, I got the job I wanted at Amazon Alexa and I owe big part of it to AlgoMonster, and even now I still want to keep using it, as I started enjoying the contents! Thanks Sheldon for creating Algo Monster, it was decisive in my journey!”

Senior SDE at Amazon
"You changed the lives of me and my brother; he even got an AWS internship from it 2 years ago. Failing a bunch of online assessments when you have no idea how other people are doing it is so heartbreaking.
Back when my mental model is of leetcode problems being all ad-hoc and there being no point to working that much at them because they are all different. Changed that whole thing up singlehandedly with algomonster, made me realize how easy it all is. Can't thank you enough!"

"Just want to thank Algo.monster team .. its the best resource to study algorithms and data structures in an organized way for the coding interview.. i got the offer from amazon for sde2 position ... once again ..
Thank you so much !"

"Wanted to say thank you to the Algomonster creators. Ill be honest, I never believed paying for anything else other than LC made sense. But not this course. I was out of touch of DS and Algorithms for 7 years, so this course helped me immensely to structure my prep thoroughly.
Studied for 2 months and got offers from MSFT, Meta and Google. Thanks to the creators
The pattern based design is awesome"

"This changed my life when it came to interviews. Because it gave me a way to quickly reach an approach. I was spending wayyy to much time on what approach to take.

These folks lay out this and then some starter templates for each approach they suggest just committing to muscle memory so that you can just start drafting the specifics"

FAQ
Anyone who has done Leetcode from scratch can understand the struggle to get started. Being presented with ~2000 coding problems can be daunting and overwhelming. Luckily almost all the problems can be condensed to a set of patterns, which are repeated over and over. All you need to learn are these building blocks, and be able to apply them to new problems. We have done the leg work of summarizing the patterns into an interactive course, so you can get up to speed as fast as possible. Think of it as it A* path-finding algorithm with AlgoMonster heuristics. Checkout the statistics we used to compile the patterns.
We have found videos to be suboptimal for learning algorithms because they are less interactive, and do not push you to think. And you really have to think when it comes to learning complex subjects like algorithms. Video is also difficult to glance through and jump around. It's often useful to go back and forth over a new concept. Kind of like how it's easier to read on a physical book than on a Kindle, it's often easier to have all the information easily accessible. Also, watching videos loses the interactivity that is built into our notebook-style articles. That being said, we do realize some people learn best with videos, so we are working on adding them. Check out our YouTube channel for video content.
Tech interviews focus on a specific set of topics. Princeton's algorithm course on Coursera places emphasis on complex academic topics, e.g. Prim's Algorithm, Krushkal's Algorithm for spanning trees, Bellman-Ford etc. These are very rarely, if ever, asked in coding interviews. It may be good intellectual practice, but usually it is not relevant.
The lists you see floating around the internet are just questions to practice. You still have to figure out how to solve them yourself, summarize and derive the intuitions. AlgoMonster does all the heavy lifting for you. Just as Issac Newton professed, we enable you to stand on the shoulders of giants.
We have a Teaching Assistant feature, an AI that is trained on all our content. You can ask it questions, ChatGPT-style, and it should answer most of your questions. If you still need help, you can always ask on our discussion forum or Discord.
If you complete the course and master all the patterns, you should be able to solve most of the problems on Leetcode and understand the discussion forums. Most importantly, you will be ready to interview for the tech role.
