I have been leetcoding for past 3 months. I have done mediums from DP, trees and graphs. I have done other topics from interviewbit.com. I have done some hard questions (not on leetcode, on interviewbit)

I have Google phonescreen in a week. Any pointers on how to revise? I have revised topics which I read during beginning of prep(DP, tree, graph). I am thinking of starting with top 100 liked questions or top interview questions. I am leaving tries, segment trees and DP bitmask for now.

But the problem is I can guess or have seen somewhere almost all of them. I can see only 4-5 questions I don't know straight away. What I wanted was a new set of questions, so I can have a general sense on how to approach? My practise has been around after knowing the category of question and doing it.

If I clear this, I will ask them 20 days. I have planned to do around 20-30 hard questions, advanced topics and system design.

Any pointers? Thanks for the help.
