In 2021, TCS introduced the National Qualifier Test (NQT) as a key step for campus hiring, and understanding the coding questions from that year remains an excellent strategy for any candidate today. The questions from that period are designed to test practical coding skills and logical thinking, not obscure algorithms. This guide breaks down exactly what you need to know, based on the actual TCS exam patterns and coding questions from 2021.
