Queries for TCS Prime Interview

Hello Everyone, I recently got shortlisted for TCS prime offer. I am doing continuous research about topics on which I should focus. But online research is confusing me. Since TCS is offering prime roles for the first time, online resources are not turning out to be that helpful.

So, please give me some insights about how I should prepare for it. It will also be helpful if I could get an idea about the interview process for Prime roles, so that I can prepare accordingly.

Moreover, this will be my first walk in interview(I have given online interviews) and I will appreciate some interview tips for that too.
