Course Overview


Course Overview

In the realm of software engineering, Data Structures and Algorithms (DSA) and System Design share a symbiotic relationship. Wondering how?

DSA provides the tools and techniques to efficiently organize and manipulate data while System Design guides the application of DSA in real-world scenarios, dictating how data should flow and interact within a system. For enabling System Designers to create scalable and designing robust and efficient performant software architectures, a solid foundation in DSA is a must. Therefore DSA and System Design are intricately connected in a way where DSA empowers System Design with efficiency, and System Design channels the power of DSA into functional and scalable software solutions.

Tailored for working professionals, our course optimizes skills for top tech jobs, leveraging DSA and System Design expertise.

I was enrolled in the System Design Live classes. I must say, Mentor and GFG support are both very professional and helpful to the students. The Mentor has a deep understanding of the system design concepts and knows the best way to teach difficult topics in it. He has cleared a ton of my doubts during the classes which helped me clear many interviews of the top-notch companies in the United States. Menor is an informative, collaborative, and interactive person who will help you in climbing up the career ladder. I would recommend this course to everyone who is starting with his/her interview preparations or has intermediate interview skills and are not sure where they are going wrong.

In addition to the DSA live for working professional, I also enrolled in the System design . Both of these Courses offers a diverse set of challenging and non-repetitive questions, which helps save time that would otherwise be spent on selecting appropriate questions. After the standard questions, the tests also provide time-bound challenges. In my opinion, the level of difficulty of the questions is sufficient for preparing for a FAANG coding interview. The GeeksforGeeks team has done a great job in creating courses that are tailored towards a specific audience with a specific goal in mind.

Live classes of DSA for Working Professional are very good and they covered all the important topics for placement in good MNC. This course helped me a lot and gives me the confidence to develop coding logic. Before this course, I didn't knew the concept of data structures but now I bagged multiple offers from TOP MNCs.

I have used GFG for a pretty long, for DSA but with time now that I am transitioning into a Senior role for System Design and it's very critical to make the cut, especially into technically rich profiles. So, this course has given me a structure to know the topics that I need to cover and expertise level at various experience levels. So, now I have the overall understanding of the concepts needed in order to do well in these rounds.

I had less experience in system design in my current company hence for further interview preparation I need to learn more about system design. This course helped me a lot in learning more about System Design. I liked the way how the course structure is designed. There are more and more practical examples that helped a lot. Mentor was also my favorite from GeeksforGeeks till now. Got to learn more about micro services high-level scalable system design. Because of this course, I was able to crack every single interview of high-level design in all big companies.

This course indeed is the right investment one can look for in gaining insights into Data Structure and Algorithms. Either a college student or a working professional can benefit from the course as DS & Algorithms is a core to crack the technical interviews & currently working as Software Development Engineer. Apart from this, Sandeep Sir's teaching is phenomenal. Thank you GeeksforGeeks for this amazing test series.

My college, Shiv Nadar University, gave us a chance to appear for an online coding test that was held on GFG itself to assess and choose students who they would sponsor for this Advanced Programming course. I was interning back then, but since I was interested in programming, I decided to appear for the same. I was fortunate enough to get selected and subsequently enrolled in this wonderful course with an extremely brilliant mentor named Sachin Chandani. The course was very evenly paced and took care of a lot of concepts that are otherwise missed out on if one chooses to go ahead and study on their own. The course started with the basic level and the weekly coding practice tests made sure that everyone was completing those in time and learning holistically as well. The environment was very constructive and we were encouraged to gain more and experiment more throughout. Had I not been enrolled on this by my college, I doubt I would have ever found this learning resource.

GFG is an exceptional platform that offers courses with well-designed, informative content. Its user-friendly interface made it easy for me to dive into the topic of DSA, which I used to find intimidating. The practice questions on this platform helped me develop my logical and analytical skills, and all of my concepts were clarified. I want to express my gratitude to the team for creating such a valuable and helpful course and platform

I am Shubham, a mechanical undergrad from IIT Bhubaneswar. I would like to thank, GeeksforGeeks for providing an immensely detailed course for the ease of students. This course has helped a non-Computer Science(B.Tech) student like me, to secure 3 offers in the software industry. Being an alumnus from IIT without any offer in hand, was very depressing for me. I bought the System Design-Live course from GeeksforGeeks and apart from this, four other courses like DSA self-paced course, CPP STL, SDE Theory, and Low-Level Design course, around 10 months back and practiced rigorously. Today I can proudly say, that I have 3 offers in hand with a base pay of 7 LPA, 10 LPA, and 18 LPA. Thanks a lot to the whole community of GeeksForGeeks. Thank you Sandeep Jain sir for making GeeksforGeeks.

Geeks For Geeks is an amazing place to learn code from starting. Being an absolute beginner, I started my coding life at GFG. First, I enrolled in Fork CPP that helped me to clear my fundamentals of C++ and start learning from the Placement Preparation Course because of the hands of the coding concept of DSA, I was able to improve my code writing skills and my problem-solving skills. to brush my skill I took the Amazon test series and participate in every event contest like Must Do Interview Preparation, Coding Round Contests - Test Series, 30 Days of Code, etc. I can say Sandeep Jain sir is an amazing, fun-loving teacher and made the class very enjoyable. The teaching assistants were very helpful and helped me learn from my mistakes. It was an amazing journey with Geeks For Geeks and I was fully satisfied with my course!! I Owe my success to Sandeep Sir and Geeks For Geeks!! Cheers!
