Conclusion :

1.Practice Aptitude

Students frequently overlook aptitude because they believe they can do it effortlessly. The fundamental point to remember is that problem-solving is not the most important aspect of ability. Everyone can answer problems with some level of mathematics that they are familiar with. However, in Aptitude rounds, it is vital to see who can solve the most issues in the shortest amount of time. As a result, speed and precision are crucial in TCS NQT Aptitude rounds. As a result, you should practice aptitude so that your speed improves and you can answer more questions faster than others.

2. Revise basics of Programming and OOPS Concepts :

The level of complexity of the programming questions in TCS Digital interviews will be moderate to high. However, knowing the programming basics becomes really crucial because we normally practice a lot of high-level data structures and algorithmic issues and get lost when asked the basics in the interview. So, whatever programming language you pick, you should review its fundamentals as well as C/C++ fundamentals, as they are frequently tested in TCS Digital interviews. The OOPS ideas are also crucial. You will not be required to solve a complex design challenge. To ace OOPS in the interview, only basic ideas of OOPS should be clear.

3. Core Computer Science Subjects should be studied well:

As previously stated, the level of questions about data structures and algorithms will be low. However, many questions are asked about key Computer Science areas such as Operating Systems, DBMS (particularly SQL), and Computer Networks (CN). Please make sure to thoroughly review them before attending the interview.

4. Resume Projects should be well revised:

There will be a lot of talk about the Projects on your CV. Please keep in mind that if your projects are based on new emerging technologies such as IoT (Internet of Things), Machine Learning (ML), Artificial Intelligence (AI), blockchain, and so on, it will have a significant and favorable impact on your interview. If you have such projects, you should be prepared to answer queries about these new and developing technologies. Otherwise, you should be fully prepared with all of the projects included on your resume. Prepare for the most common questions, such as "Why did you use this particular technology?" and "What problems did you have during this project?"

5. Work on your Communication Skills

Your communication abilities will be tested throughout the interview. Even if you know the answer to the most difficult questions in the interview, you will have difficulty explaining your solution. As a result, we propose that you concentrate on your communication abilities. Some simple guidelines can be followed to improve soft skills. For example, if you revise a previously studied section, read it aloud in English as if you were explaining it to the interviewer. Mock interviews can help you improve your soft skills and boost your confidence in interviews.


This format of TCS Digital is being followed from previous year. Though practice and consistency is the key to crack TCS Digital, it is recommended not to mug up the previous year questions blindly, and instead, try to understand the format and practice accordingly for better results.

Good luck and ALL THE BEST!!!!!
