First step for TCS is to qualify NQT with good score. Only top candidates get chance to sit at TCS digital written test. It is not hard to crack written paper if you are good in programming and coding mcq’s you only require to put some focus on Aptitude section. English section is very easy in both the examination NQT as well as TCS Digital written test. Coding mcq’s section mainly consist ‘C’ mcq and some questions related to ‘C++’ and ‘Java’ also. (one thing should be noted that if you are python programmer than you have some idea about python 2.7 syntax)
