Tata Consultancy Services Software Engineer interview questions

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.
