There are people having similar experiences like you , for example :
https://discuss.codechef.com/t/tcs-nqt-2021-digital-interview-results/81780/90?u=youknowmee
Most of the interviews have been completed all across India .
Maybe you already gave TCS interview through Codevita, hence you cannot get an interview 2 times .
They most probably missed you . Happened to one of my friends as well. Or maybe you preformed bad in the digital exam , hence they did not shortlist you for the interview .
Have high hopes , you deserve better!!!
