TCS Digital Interview Experience (through Codevita 2019)

Last Year I got Selected as System Engineer in India’s Biggest IT Company TCS. 
I got Selected Not through NQT(National Qualifier Test) but through the CodeVita. 
The Role Offered to me was the Digital. 

So let’s have some prior experience before actually sitting in the Interview Room. 

Initial Phase : CodeVita 2019 Exam 
The CodeVita is one of the Famous Coding Competition not in India but also outside India. 
It not only gives you the opportunity to show off your coding skills but also gives you the chance to have a Job Interview with TCS. 
The CodeVita Contains around 6 Questions with 6 hours to submit your Test. 
Once you start your test then only you would be able to see the question and your timer for 6 hours will start automatically. 
The Codevita usually Contains around 3 easy 2 medium and 1 hard questions (It may vary with the year). 
If you are able to solve one of them you will get the interview opportunity as many of my college friends who had solved only one question got the interview opportunity. 
Luckily I was able to solve 3 out of them. 
A few days later to the test I got my ranking and offer for the interview and received information regarding the Documents that I need to carry to the Interview room with the Interview Location.
