TCS Digital interview experience || How to prepare for TCS Digital

Описание: This video shows TCS Digital interview experience. I have described each round sufficiently well and have posted the questions below.

ROUND 1: National Qualifier Test (NQT) Don't attempt questions which you don't know which contain negative marks. Try attempt the code even if you know that you won't be able to get the right answer. If you don't attempt then you are sure to fail. I have seen people who attempted, got selected for interview.

ROUND 2: Interview: Don't panic. Just study the recent technologies, ML and AI along with the questions posted below and you will be ready to rock :D
