TCS

I recently attended the TCS Prime interview process, and I would say the overall experience was good and the process was quite manageable if you have a proper understanding of the basics. The first round was the online assessment, which followed the usual TCS pattern. The numerical ability questions were of medium difficulty. They were not extremely difficult, but I felt that practicing aptitude questions beforehand would definitely help with both solving speed and accuracy. The verbal section was comparatively easier. There were questions related to passage recall and vocabulary, and I found those sections relatively easy. There were two coding questions in the assessment. One of them was based on the Two Sum problem. The other question was related to finding the sum of numbers that were present in pairs. Overall, the coding questions were manageable and were based more on understanding the problem and implementing the logic properly rather than requiring very advanced DSA knowledge. After clearing the assessment, I attended the final interview. The interview had a mixture of technical questions and some questions related to flexibility and work requirements. It started with the usual "Tell me about yourself" question, after which the interviewer moved into questions based on the technologies and topics I had mentioned. One of the questions was about the difference between React functional components and class components. I was asked to explain how they differ and the basic idea behind them. I was also asked about middleware, where I had to explain what middleware does in backend development and how it works between a request and the final route or response. The interviewer also asked questions related to DevOps. I was asked about the difference between DevOps and DevSecOps, followed by questions on the DevOps lifecycle. I was also asked how CI/CD can be implemented. The discussion was mainly around understanding the overall process, such as how code changes are integrated, tested, and then deployed through an automated pipeline. There were also questions related to NLP. I was asked how text is converted into numbers for processing in an NLP or machine learning model. I was also asked what needs to be imported for doing this. So, I would suggest anyone mentioning NLP or machine learning on their resume to be clear about basic concepts like text vectorization and methods such as Bag of Words or TF-IDF, along with the libraries used for implementing them. Towards the end of the interview, there were a few straightforward HR and availability-related questions. I was asked whether I was willing to relocate, whether I was comfortable learning or working with new technologies, and whether I was willing to work night shifts if required. These were mostly direct yes-or-no questions. Overall, I felt that the final interview was mainly focused on checking my understanding of the technologies I had mentioned rather than asking very difficult or unexpected questions. The questions covered React, backend concepts like middleware, DevOps and DevSecOps, the DevOps lifecycle, CI/CD implementation, and basic NLP concepts. My suggestion for future candidates would be to make sure they understand the fundamentals behind every major technology they mention in their resume and are able to explain them in a simple way. The overall TCS Prime process was a good experience, and I felt that the questions were manageable with proper preparation, especially in aptitude, basic coding, and the core concepts of the technologies mentioned in the resume.
