Can anyone guide me through luthra internship?

I got the confirmation and i am assigned to Corporate Restructuring, Regulatory & Compliance Team under Mr. Harish Kumar.

How to get a call back and a PPO interview?

I am currently in my 3rd year and will be completing my 3rd year in April.

Dude ,third year is too early to think about a callback or PPO.and . assuming you're from an NLU, so don't bother you'll get a calllback anyway .
