First we have to cleared the TCS ION test. If you can able to solve both the coding questions then you can eligible for the Prime role. The interview was quite easy. The interviewer was made me comfortable. The offer letter was issued within a week.

The interview was comparatively easy. Most of the questions were basic and directly related to the topics mentioned on the resume. The interviewer focused on verifying whether the candidate genuinely understood the technologies and projects they had listed, rather than asking advanced or unexpected questions. They asked fundamental questions such as explaining projects, the technologies used, design decisions, basic programming concepts, and core computer science subjects relevant to the resume. There were very few trick questions. If you have a clear understanding of everything you've included on your resume and can explain it confidently with examples, you should be well prepared. The key is to avoid listing skills or technologies that you cannot explain in detail, because the interviewer may ask follow-up questions on any item mentioned in your resume.

The interview started with a brief self-introduction, followed by questions about my coding experience, including how many coding problems I had solved on the NQT platform. The interviewer then asked me to write a sorting algorithm on paper, explain its logic, and modify it to sort the array in descending order. After that, the discussion moved to C programming concepts such as `malloc()` and `calloc()`, including their differences and use cases. The interviewer also asked fundamental DBMS questions and SQL queries, including writing a query to find the second-highest salary from an Employee table. Later, I was asked to explain the projects mentioned in my resume, focusing on the technologies used, my contributions, challenges faced, and how I solved them. The interview concluded with several situation-based questions to assess my problem-solving ability, communication skills, and approach to handling real-world workplace scenarios.
