As a developer without formal education I struggle to solve algorithm formulas.— Vignesh M (@ShivEnigma) August 31, 2020
I always tend to use loops and arrays for everything. In the web languages I used, the other data structures are not very obvious.
I improved a bit for a while using https://t.co/QoQUVYT4Ze

Jumping into problems can be tough. We've compiled all that you need for a technical interview. Our lessons not only teach you the concepts, but engage you with visuals, running code, and questions. Whether it's linked lists or tree traversals, you'll be sure you're well prepared in the most efficient manner.
The most important part of getting better at programming interviews is understanding the right approach. Every interview question on the site has a thorough, step-by-step explanation with code snippets and visuals. Never get stuck on a problem again.
Level up your interviewing abilities every day by receiving problems in your inbox and solving them right on the site. Free to all users, the daily email helps you stay on track with a question a day. Land a job with the full course, which unlocks access to hundreds of lessons and problems.
You already know that the top software companies have standardized on a type of coding interview. These interviews usually test your knowledge of data structures, algorithms, and systems design. But such Computer Science fundamentals aren't easy to learn, especially for those of us from a non-traditional engineering path.
Have you worried that not getting these concepts might be holding back your career? Or been stuck for hours on a Leetcode easy problem? Or been frustrated with not "seeing the patterns" after hours and hours of problem solving?
I was in your shoes. After learning the basics of how to code, I wanted to land a software engineering job. However, I kept getting data structures and algorithms problems during interviews, and they made no sense to me. When I prepared, I was confused by the mathematical notation, intimidated by how much I had to keep in my head, and found it difficult to stay motivated.
I wanted to focus my limited time to just the most common problems. I needed to see things visually, and in many different ways, before it clicked internally. And above all, I wanted a coach that would not only focus on the interview, but came with the understanding that the coding interviews were just one part of an overall application.
Hi, I'm Jake! I've been in software for about a decade, first as a project manager and then an engineer. I've worked at all sorts of places, from high-growth startups to the leading tech giants. When I was transitioning to being a developer, I found academic resources to be dry and hard to understand.
I wanted a learning system that slowly but surely built up my Computer Science fundamentals. I wished that the books and articles were written in plain English, and not as though it were meant for academia. And above all, as someone who learns best by seeing and doing, I yearned for more visual, interactive ways to master the material.
So my team and I built the resource that we wanted. That's where AlgoDaily's full technical interview course comes in.
It's not just you-- these are difficult concepts for anyone to grasp by themselves. This scarcity has caused top software engineering jobs to pay eye-popping compensation numbers. However, we believe that anyone can become fluent. In fact, it doesn't have to be a grind. You simply need a system that teaches you the right way.
For each concept, you are guided to intuition. We always start with a gentle introduction. Then we teach the patterns to crack any problem using that concept. Only after you're well equipped with the fundamentals, do we start drilling interview problems in a progressional way.
You're a busy professional, and don't have all the time in the world to make sense of these fundamentals. Our philosophy is that systems, rather than raw willpower, help you achieve your goals. You need motivation that is automatic, hard to avoid, and predictable.
We've sliced up the curriculum into actionable chunks. Our cornerstone daily emails and 60 day crash course give you the lessons to read and challenges to solve each day to ensure that you stay on track.
To make sure you're retaining what you're learning, we provide questions within our lessons and walkthroughs. It ensures that recall is high, and that you won't stumble on small details when you need them.
We think it's best to learn by doing. There are many daily coding email sites, but we're the only one with a fleshed out coding environment. Test code and try things out to get better at algorithmic thinking. Then go through our amazing walkthroughs so that you perform well on game day.
Unlocked lessons and challenges will always be free.
But for the price of a fancy dinner, enhance your career and double your pay at your next job.
Our students have increased their annual compensation in the range of $5,000 - $76,000*.
We go beyond algorithms and data structures, and teach you how to learn and succeed as a developer.

Are you a coding bootcamp graduate, self taught developer, or career switcher? Or otherwise thinking about breaking into software? If so, you've reached the same conclusion as us. Most of the material out there promises to help "crack coding interviews". But you start working through the material, and you instantly fall asleep! Instead of just nerding out about algorithms, data structures, and systems design (which we do too!), our focus is on helping you land your first software engineering job-- while appreciating that folks have different learning styles.
Ever thought: what are these mathematical symbols? Time complexity makes absolutely no sense. Whiteboards and graphs scare me. Am I smart enough to get this stuff?
I'm here to tell you are smart enough, but it's more about how you're introduced to the concepts and the approach you take. Many software companies now use standardized technical interviews. We're here to help non-traditional developers feel prepared for them.
You're not traditional, and neither are we.
AlgoDaily was created to help developers level up in their careers. We teach people how to break into the industry and build amazing programming careers. We're designed for those who have not taken a formal Data Structures or Algorithms class (or for those who feel like they didn't get it the first time).
We teach by making things daily, guided, and visual.
Our flagship product is our online course that helps ambitious developers land jobs. In it, you'll find nuggets of career wisdom and guides on every aspect of the technical interview. We also offer in-depth, step-by-by step walkthroughs for hundreds of real interview problems.
Given our namesake, as you might expect, we also have a free daily newsletter. It comprises of a technical interview question every day, for 100+ days. The problem sent is based on where you are in the AlgoDaily list of challenges.
We've designed our course to optimize for developer happiness. Over 15k developers have used our course or course materials. They talk about how they're finally prepared for grueling technical challenges. That the problems we covered helped them pass real interviews with confidence. And how they finally realized, believe it or not, that interview prep could be fun!
The course is written in plain English, and only teaches the essentials of what you need to know for technical interviews.
Finally, we are built for visual learners, and thus have hundreds of videos, illustrations, and code visualizations.
1. We are not a question bank. So many sites and courses just give you problems to solve-- we teach you the fundamentals, the patterns, the approach, and the inner game of interviewing-- step by step.
2. Our illustrations and visualizations: no other resource has such beautiful, helpful artifacts accompanying each guide. Professionally curated diagrams and the ability to step through code are priceless for visual learners. All of our artifacts are made by programmers with a design background, ensuring that comprehension comes with aesthetics.
3. Other technical coding interview courses are often taught by junior engineers who haven't actually spent times at tech companies. Jake has worked across multiple startups and large tech firms, and has been an interviewer and an interviewee. Our contributors are typically Computer Science professors, teaching assistants at prestigious universities, or professional software engineers.
4. Rather than give you the solution, we teach the approach. Weigh the time and space complexities with every problem. Every challenge on the site is walked through our CTPBO approach, so you get into a habit of thinking the way you should on game day.
5. We teach via recall. By forcing you to tackle smaller hint questions as you think through challenges, we are priming your brain to remember concepts better.
6. We provide videos for the majority of our lessons and solutions, so you're always seconds away from clarity.
Finally, our active community, running cohorts, and standard to help makes sure you're not alone.
It's 100% free to sign up! All members can try to solve all of the technical problems, as well as access existing problems and lessons which are being developed.

AlgoDaily is designed for:
The lead instructor and founder, Jake, is an engineer with a decade of experience, interviewing and being interviewed, at several top software companies and financial firms. The rest of the team consists of programmers with backgrounds in career coaching, design, and technical writing.
When we made AlgoDaily guides and solutions free, we found that users were completing less problems. Paying for the material is an intrinsic motivator to ensure that you actually put in the hours to learn to interview well. It helps to have skin in the game. Additionally, we want to maintain a high standard for AlgoDaily content-- which means hiring world-class talent to produce the lessons, walkthroughs, and visuals.
Getting a software engineering job goes beyond just interviewing well. To even get the interview, you need to ensure your resume's solid, you have a referral in, and you can make a good impression. Not all of this is intuitive, so we ensure that those lessons are also included.
We are targeting full C#, Go, and Ruby support by end of Q2 2021.
We have found that the one-problem-a-day approach to preparation is a good cadence. Most people will start studying for their interviews roughly 1-3 months out, which ensures that about 30-90 problems are seen. We recommend going through How to Prepare for a Technical Interview for our thoughts.
In our experience, 30-90 focused problems that specifically focus on any gaps in knowledge are all that's necessary to feel confident come interview time.
Not a problem, we understand that AlgoDaily is not for everyone. If at any time you are unhappy with your subscription, we are happy to stop your membership immediately or grant a refund within 14-days. Simply email us.
