Interview preparation journey

Journey
My name is Vamshidhar. When I started my B.Tech degree, I had no prior expertise with coding or programming languages, which made it challenging for me to get past the barrier of addressing a problem before first seeing the solution. However, I decided to learn how to code. I watched numerous YouTube courses but did not find much success. Eventually, I enrolled in a Python and DSA course from Coding Ninjas, which greatly assisted in honing my skills. To the best of my ability, I continued practising DSA over time. Although I didn't start preparing for DSA until after my first year, I studied the principles of problem-solving diligently. With time and experience, I was able to solve problems considerably faster, and I can honestly state that DSA was the key to my success with TCS Digital. After submitting my application for an off-campus pool drive and passing the coding tests, I was invited for an interview.
Application story
Our college forwarded the URL to apply to TCS's pool drive, which was open to all South Indian colleges. As a result, there were two coding rounds: one based on hacker rank and conducted online, and the other was a technical interview. Once you advance past these stages, you are chosen.
Why selected/rejected for the role?
In the initial two rounds of the interview process, my capacity for problem-solving was evaluated. I was intrigued by full-stack development and had a firm grasp of DSA. I accomplished numerous good tasks in this area that allowed me to show the interviewers my skills.
