Opting the data structures and algorithms course from Geeksforgeeks was the best decision of my life. It boosted my placement preparation, and a month of self-practice was all I needed to clear the rounds of various companies. The portal had selective questions on every topic for practice, which eventually helped me to land up a job at Wipro.

I am Tamal Mondal, a final-year MTech CSE student from IIT Hyderabad. I enrolled in the "Complete Interview Preparation" course on the GFG platform to prepare for the 2023-24 placement season. The course is a good value for money. Firstly, the course is very well structured and it covers almost all the topics in Data Structure and Algorithms with solutions of the most popular coding problems from each topic. The interview preparation course also provides materials for core subjects, aptitude questions, and OOPs concepts, making the course comprehensive and a one-stop solution for placement preparation.

Being a student from ECE background, I always struggled while coding. But after opting this course from GeeksforGeeks, things became much better with the proper guidance and study material provided. The mentors were so friendly and helpful that they would dedicate extra time to clear our doubts. The whole 2 month course gave me the confidence to appear in the IT companies.

I am very glad that I have got placed in Aaum Research and Analytics as a data scientist. At the initial stages of my BTech, I was too frustrated and I am so confused about where to learn and how to develop my logical thinking. At that time GeeksforGeeks played an important role in my life developing skills from very scratch, motivation and patience developed my skills. I used to be very frustrated when I used to have errors in the code but to my mind, Sandeep sir told me one of the finest tricks have patience and belief and overcome the problem. I am very motivated by his kind words and another thing he told me "Struggles are the milestones for success" .Struggling means knowing your mistakes here comes me as a data scientist. One among every one wants to become this only few who face struggles come with the best monuments in their life. Thanks, GFG for everything along with emotional and moral support. I am confident that even I can be successful.

I had applied for the Geeks for Geeks course mainly for training and placement purposes. I had a great experience and I got to know a lot about the types of questions frequently asked in companies, and many more. The course also helped me to brush up my coding skills and work on my grey areas. The course helped me in getting placed with great companies as well.
