Updated for 2021 hiring season! Join a live online community of over 400,000+ developers and a course taught by an industry expert that has actually worked both in Silicon Valley and Toronto as a senior developer. Graduates of this course are now working at Google, Tesla, Amazon, Apple, IBM, JP Morgan, Facebook + other top tech companies.
Want to land a job at a great tech company like Google, Microsoft, Facebook, Netflix, Amazon, or other companies but you are intimidated by the interview process and the coding questions? Do you find yourself feeling like you get "stuck" every time you get asked a coding question? This course is your answer. Using the strategies, lessons, and exercises in this course, you will learn how to land offers from all sorts of companies.
Many developers who are "self taught", feel that one of the main disadvantages they face compared to college educated graduates in computer science is the fact that they don't have knowledge about algorithms, data structures and the notorious Big-O Notation. Get on the same level as someone with computer science degree by learning the fundamental building blocks of computer science which will give you a big boost during interviews. You will also get access to our private online chat community with thousands of developers online to help you get through the course.
Here is what you will learn in this course:

* Arrays
* Hash Tables
* Singly Linked Lists
* Doubly Linked Lists
* Queues
* Stacks

* Tries
* Graphs
3. Algorithms:
* Recursion
* Sorting
* Searching
* Tree Traversal
* Breadth First Search
* Depth First Search
* Dynamic Programming

Unlike most instructors, I am not a marketer or a salesperson. I am a senior developer and programmer who has worked and managed teams of engineers and have been in these interviews both as an interviewee as well as the interviewer.
My job as an instructor will be successful if I am able to help you become better at interviewing and land more jobs. This one skill can really change the course of your career and I hope you sign up today to see what it can do for your career!
Taught by:
Andrei is the instructor of the highest rated Web Development course on Udemy as well as one of the fastest growing. His graduates have moved on to work for some of the biggest tech companies around the world like Apple, Google, JP Morgan, IBM, etc... He has been working as a senior software developer in Silicon Valley and Toronto for many years, and is now taking all that he has learned, to teach programming skills and to help you discover the amazing career opportunities that being a developer allows in life.Â
Having been a self taught programmer, he understands that there is an overwhelming number of online courses, tutorials and books that are overly verbose and inadequate at teaching proper skills. Most people feel paralyzed and don't know where to start when learning a complex subject matter, or even worse, most people don't have $20,000 to spend on a coding bootcamp. Programming skills should be affordable and open to all. An education material should teach real life skills that are current and they should not waste a student's valuable time.  Having learned important lessons from working for Fortune 500 companies, tech startups, to even founding his own business, he is now dedicating 100% of his time to teaching others valuable software development skills in order to take control of their life and work in an exciting industry with infinite possibilities.Â
Andrei promises you that there are no other courses out there as comprehensive and as well explained. He believes that in order to learn anything of value, you need to start with the foundation and develop the roots of the tree. Only from there will you be able to learn concepts and specific skills(leaves) that connect to the foundation. Learning becomes exponential when structured in this way.Â
Taking his experience in educational psychology and coding, Andrei's courses will take you on an understanding of complex subjects that you never thought would be possible. Â

Reviews
Great course I like the way of his teaching easy to understand it. Like the content I had a great time of learning thanks Andrei.
this was perfect! exactly what anybody new to ds and algo needs to learn. only improvement i would suggest is to include more steps wise exercises rather than implementing ADTs
Perhaps I picked the wrong course, since I was only interested in improving my algorithmic skills. Also, getting a job as a software developer is not at all realistic right now given my lack of skills and not knowing what exactly I'm interested in. But this course did clarify a lot of things I didn't understand, especially regarding data structures like linked lists, trees and graphs. I still have a lot of questions, but I'm sure they will be answered with enough studying and through creating my own projects. Also, knowing how the interview process works is is good.
This is a good course. Andrei did a great job as usual. I think this course could be shortened a bit.
I found this course to be very informative. Teaches you so much more than just how to be a knowledgable programmer. A nice in depth data structures section, what to expect during the non technical interview and more. My only complain is the algorithms section. I feel that this section is rushed and deserves a bigger emphasis. Algorithms is just as important and if not more important than data structures. As for DFS/BFS I believe this section should have revolved around mostly graph implementation and not trees. The graph implementations are more challenging and shows the true depth of BFS/DFS in my opinion. Overall this was a great course and I have already purchased another course by Andrei. Thank you!
Very good information and I learned some of the data structures that I only knew about but never had implementation hands on. Many thanks.
The instructor is very knowledgeable in the area and gives excellent examples and advice on what companies are looking for. So far it is an amazing course and I enjoy the way the instructor communicates the material. Very informative, well organized and thorough. I look forward to completing the course and putting in practice what I learn. Thank you for sharing such a great course.
A cool course, with good explanation of each topic. He explains everything when needed means he's not jumbling up in the course.
I enjoyed this course so much. It covers everything an employee may face in his interview and how to get the best offer from different companies. For the technical part, this course shows many questions a programmer may face in google, Facebook, amazon, etc.
the course nobly aims at trying to cover way too much concepts but fails to do so fairy in many places, you can sense poor content
Most of the interview there is more stress on problem solving with DS. I think this course takes you through basics but leaves advance topics of implementation those basics.
Great course, great content. The only issue I have is that he ends up rambling quite a bit. Sometimes makes for hard listening. You just want to get to the point.
I am looking for a developer job. But finding a good mentor who guides you to this journey is a difficult task. So I find this course which sharpens my technical skills and help me to find at a better position to get those jobs by using the non-technical areas where I think need to work upon. This course is by now the best one I am looking for as a developer.
One of the best courses I've ever taken on Udemy. Being an astronomer-turned-into-Data Scientist, I've always found myself in the in-between Statistics and Programming; this course helped me to improve a lot on the latter, with clear, fun and helpful explanations. The instructor is very captivating and I definitely recommend this course! Thank you and congrats for the awesome work, Andrei!
It was somewhat more basic than I needed. A course for experienced programmers would have been more time efficient for me.
