Number of Rounds: 3

Topics Asked: Coding: Max value in 2D matrix (Python), max frequency character in string, datetime parsing. Technologies: Python, Flask, SQL, React, HTML, CSS, JS, Rust. Conceptual: Why Rust is used, AWS Lambda basics, Git commits/hash URL, SQL engines and datatypes.

The TCS Prime interview process began with the TCS NQT exam, a computer-based test held offline at TCS-ION centres, which included numerical ability, general aptitude, verbal ability, and two coding sections. The non-coding sections required speed (about one question per minute), while the coding sections allowed languages like Python, C++, Java, Perl, and Delphi, with 30 minutes for the easy problem and 60 minutes for the advanced one. Unlike platforms such as LeetCode or GeeksforGeeks, candidates had to handle input/output manually, and I successfully solved both coding problems. After clearing this stage, I was invited for the Prime category interview, which was conducted by a panel of three members—HR, Manager, and Technical—and lasted around 20–25 minutes. The technical questions included writing Python code to find the maximum value in a 2D matrix, writing code on paper to find the character with maximum frequency in a string, explaining technologies I know (Python, Flask, SQL, React, HTML, CSS, JS, and interest in Rust), why Rust is used, AWS Lambda basics, Git usage, SQL engines (SQLite, MySQL), SQL datatypes (TEXT, INT, DATETIME), and parsing a datetime string in Python using strptime. I also explained two of my full-stack projects. The HR questions focused on leadership qualities, workplace integrity, shift rotations, motivation, and past interview experiences, along with self-analysis of why I wasn’t selected earlier. Finally, I asked about joining timelines and training expectations. A week later, I received an offer for the Digital Role.
