Hello Good People

I genuinely need some help. I have my Google telephonic interview scheduled soon.

I have been putting all the efforts but I want my efforts should go in right direction.
I went through Google Card on Leetcode but they are bifurcated as per topics.
Currently my focus is to get through the telephonic round.
Plese guide me in the right direction. If any specific topics or set of problems you folks think must be covered please mention in the comments below.

Would really appreciate the hlep. Thank you so much in advance.
