Flipkart UI machine coding query

Hey all, I have a machine coding round coming up at Flipkart for Frontend SDE-2 position.

I wanted to know a couple of things -

1. Will it be vanilla JS or any framework specific ?
2. Is googling syntax/methods allowed in case you are stuck ?
3. Interview is for 2 hrs almost, what will the interviewer be doing? lol

Please any insights will be helpful!
