I had this view when I was interviewing for internships during this quarter. I have spent working and interviewing at a couple of places, before I came to pursue my masters and I believed people valued coming up with the solution on the spot.
I interviewed at atleast 10 places for internships and every single of them asked one of the questions from either leetcode or cracking the coding interview. I found none of them cared whether I am thinking on my feet for a solution or not. As long as you can reproduce the answers to the questions in a nice manner, you got selected. None of my interviewers were trying to understand / empathize how difficult it is to come up with a solution really quickly when you have not seen the problem before.
The thing I learnt through the ordeal is
1. Nobody cares whether you are thinking on your feet or not.
2. You need a month of preparation going into these sort of interviews.
