Tata Consultancy Services Assistant System Engineer-Trainee interview questions

Faced the interview in virtual way during carona, interview process is very keen and perfect. No issues faced during interview I have faced 3 rounds i.e., Tech round and MR and HR Have asked me to solve programming question Also asked about educational background And then few questions around electronics and communication background

I attended a TCS Prime interview, Questions were mostly about the new technologies and the different work situations which I personally think I answered well. Only few terms were asked which I have zero knowledge about, I even wrote the code they asked but I only got a Ninja offer. And some of my friends with bad interview experience got digital offer. I don't understand how they select the candidates. Very much dissatisfied with them. Never applying again.
