What are People who got selected for TCS Digital says about their experice:

After registering for NQT, I got the exam email. I got the exam link and credentials, a day before the exam. 

The pattern for the exam constituted of:-

Foundation round- which contains basic questions from traits, verbal, logical as well as numerical ability. The given time was 76mins 

Advanced Round- duration was 90mins.

 This section had questions from advanced coding, quants and reasoning abilities.

For coding questions, the first question was based on string manipulation. The second question was based on dynamic programming and was a bit difficult compared to the other questions.

Most of the questions seemed easy and were common with what I practiced. Even the coding questions were easy. One question was on loops and the other was on string manipulation.

My overall takeaway from this round was that it was of easy to moderate level.

I got shortlisted for the interview in the TCS Digital profile after clearing both the foundation and advanced coding sections of the written assessment.

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!!!!!
