Course Description

Welcome to the Complete Data Structure & Algorithms: Technical Interviews course

Data structures and algorithms is not just a subject which every programmer should master but also a major topic in technical interviews by giant technology companies such as Google, Amazon, Microsoft, Netflix, Uber, Tesla etc.

Not only we will learn about the theory and practical implementations of the data structures & algorithms but also we will solve many technical interview questions and practice what we learn in each section.

During the course we will use Python programming language for all implementations and question solutions. However if you are sufficient in any other programming language before, you would be fine. We have a quick Python Refresher section where you can learn about the fundamentals if you want to adapt. Alternatively you can learn all the algorithms and solutions and implement them in your own preferred language as well.

This course is brought to you by Atil Samancioglu, teaching more than 300.000 students worldwide on programming and cyber security along with the Codestars, serving more than 1 million students! Atil also teaches mobile application development in Bogazici University and he is founder of his own training startup Academy Club.

Some of the topics that will be covered during the course:

  • Technical Interview Questions

  • Big O Notation

  • Stack

  • Queue

  • Deque

  • Arrays

  • Linked List

  • Heap

  • Graph

  • Tree

  • HashTable

After you complete the course you will be able to solve technical interview questions, improve your programming skills and implement ideas in real life problems. You will be given many opportunities to solve questions on your own during the training and it will be vital for you to follow these instructions.

If you are ready, let's get started!

Very good explanation, amazing instructor, simplifies things really well

By Pradip Rajendra Yenpure on 3/30/2026

explanation and practical discussion not good according to concepts

By Bill Campbell on 10/3/2024

There are many problems with solutions that facilitate the learning process. Questions are answered by the instructor promptly. Great course!

By Iuga Marian Silviu on 2/3/2023

Very good course. I like the concept of O(n) notation that in short is making things more efficient by targeting the upper middle value a few times like to reach improve 300 no need to get directly 300 at first iteration but try to improve using iterations similar to 150 225 275 287 300.

By Yusuf-Rasheed Reed on 2/2/2023

So far Big O notation is explained very clearly. This is a refresher for me by the way since I had this concept in college but that was many years ago.

By Bilal Khan on 1/3/2023

Best DSA course so far, worth spending time , others can definitely do well if they practice , However some 50-60 questions with answers as an assignment would have been great. Kudos to the instructor...

By Charles K. Summers on 7/28/2022

My primary language is 'C' so I had to think of how I would implement all of the various parts of Python3 that are inherent. Some questions/discussions need much more practice with after the course. Ideally, a person would do the exercises on their own before heading to the next question. However, that would expand the time needed a lot.

By Kevin Smead on 7/21/2022

This is a great course to learn more about programming in general and python specifically. This class is helping me develop the confidence I need to take the next steps to becoming a professional programmer. As always, Codestars delivers in a big way.

So far, great and clear explanations by the instructor!
