TCS NQT Sheet 2027 - Coding Questions, Aptitude Practice, Exam Pattern and Syllabus

The TCS National Qualifier Test (TCS NQT) is an exam Tata Consultancy Services uses to screen candidates for entry-level roles. We put together this TCS NQT 2027 preparation sheet to help you practise for the exam and get ready for the technical interview. Start with the 150 coding questions below, then use the lessons, practice sets and topic mock tests to work on quantitative aptitude, logical reasoning and verbal ability. Further down, you’ll find the section-wise syllabus, exam pattern and technical interview resources. The guide also shows you where to check eligibility and exam dates for your batch, and how to apply.

150 Coding Questions for TCS NQT

Coding is one of the most important parts of the TCS NQT exam for IT roles. We handpicked the 150 coding problems below based on the TCS NQT exam pattern and the types of questions asked in previous exams. Start with basic programming questions and work your way up to more challenging problems on data structures and algorithms (DSA).

TCS NQT Aptitude, Reasoning and Verbal Practice

Along with coding, the TCS NQT exam tests your quantitative aptitude, logical reasoning and verbal ability in the Foundation section. We’ve put together lessons, practice questions and mock tests for 47 topics to help you prepare for all three areas. Start with a lesson to learn the basics, then solve the practice questions and take a mock test on the same topic to check your progress.
