TCS NQT Syllabus

 

What does this sheet Contains ?

This article contains TCS coding questions i.e. the coding questions that are mostly asked in TCS hiring challenges on different topics. The questions are arranged topic-wise in this sheet along with their solutions.

TCS Ninja and Digital profiles are selected on the basis of the TCS NQT test score. These two profiles differentiate the employees on the basis of coding and interview experience.

  • TCS Digital: TCS Digital hires for the Digital Technology Domain, specializing in IoT, AI, ML, Big Data, Virtual Reality, BlockChain, NLP, etc. There are three ways of landing the TCS Digital offer.
  • TCS Ninja: TCS Ninja profile is hired through TCS NQT test, based on the score you scored in NQT you will choose as Ninja. It offers package of 3.36 to 3.60.

Verbal Ability: In TCS NQT there are 25 questions and the given time was 75 minutes to check your proficiency on English, like easy writing and questions answering.

 

Aptitude & Reasoning Ability: Here in this Aptitude & Reasoning test the numerical and the reasoning ability sections are tested. We attached 10 set to practice yourself.

 

Programming Logic: Your knowledge of C, C++, and Java is tested in the TCS NQT Programming Logic exam, but that is not its only purpose. To answer questions like OOPS, DSA, etc., you must have a solid grasp of computer science Concepts There are a sufficient number of Data Structures Problems. To prepare you for the test, let’s first go through the fundamental guidelines

  • Data Structures:A data structure is a storage that is used to store and organize data. It is used for processing, retrieving, and storing data. There are different basic and advanced types of data structures used in almost every program or software system that has been developed.

  • Algorithms:Algorithm refers to a sequence of finite steps to solve a particular problem.The word Algorithm means ” A set of rules to be followed in calculations or other problem-solving operations ” Or ” A procedure for solving a mathematical problem in a finite number of steps that are frequently by recursive operations “.

  • OOPS Concepts: As the name suggests, Object-Oriented Programming or OOPs refers to languages that use objects in programming, they use objects as a primary source to implement what is to happen in the code.Object-oriented programming aims to implement real-world entities like inheritance, hiding, polymorphism etc.

 

Coding Section: In the Coding section of TCS NQT, they asked questions from the below-mentioned topics:
