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.

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.

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.

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!

This course is an excellent resource for interview preparation. I want to thank GeeksforGeeks for providing an outstanding course that covers all of the important questions that are needed to succeed in technical interviews and online assessments. This course helped me to solidify my understanding of data structures and algorithms and prepared me for a software engineer job interview. It provided a step-by-step approach to learning the concepts from the basics to more advanced topics such as trees, graphs, and dynamic programming. I am grateful to Sandeep Jain and the entire GeeksforGeeks team for creating such a valuable course at an affordable price and for building this amazing platform. The questions in the course are of the same difficulty level as those asked in interviews and online assessments

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.

Completing the "DSA to System Design for Working Professionals" course, anchored by the "Mastery in DSA," was a game-changer. From refining my coding skills to seamlessly applying them in real-world system design scenarios, this course is a practical investment for any professional serious about software development.

I was able to develop my coding skills through this course. The training had industry oriented problems that required extremely sound logic, but the mentor took his time explaining every line of code and giving homework assignments similar to the training problems. Everyone should take this course, in my opinion.

I purchased a bundle from GeeksforGeeks and used it to prepare for online tests and interviews by taking all of the mock tests and solving most of the problems. This series was very helpful for me. Thank you, GeeksforGeeks.

I found this bundle to be the best for software engineer because it covers all of the core questions and provides an effective way to master each data structure. The test series has a good selection of questions from each topic of data structures and algorithms. The Preparation Guide included in the course was also very helpful for me as I started my interview preparation journey. To prepare, I followed a strategy of reading about the data structures and algorithms on GeeksforGeeks blogs and practicing the problems provided for each one. For revision, I found that taking online coding assessments was the best way. To challenge myself, I also took the mock rounds included in the test series. Overall, this test series was very helpful for me. I wish you the best of luck on your preparation journey.

"I had always struggled with data structures and wanted to transition from a support role to a development role. This course not only helped me land a job that allowed me to work with the latest technologies, but it also greatly improved my skills in data structures. The live classes, study materials, and videos provided were very thorough and descriptive. I highly recommend this course to anyone."

Once I had basic knowledge of Data Structures, I started using the questions to practice questions based on topic and difficulty levels. Whenever I felt like in need to brush up some Data Structure or Algorithm, I used to practice them from the portal. The question sets covers most of the important and reoccurring problems that are commonly asked in tech interviews. Going through the problems made me confident that I can clear most of the interview round based on Data Structures & Algorithms.

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.

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.
