PhD Google interview with a coding round

Hi all,

I have a PhD Google interview with a coding round within 3 weeks. I need your help. Please suggest what all to refer. Also what all topics, I should focus the most. I want to focus on easy to medium level questions with no dynamic programming. I have to give my 100%. Responses from Google engineers will help me a lot.

Edit: My PhD is on Deep Learning and Medical imaging. So I have worked on frameworks like pytorch tensorflow keras. Also I dint apply. Directly I got a call. Regarding resume achievements, I have 1 patent and 4 papers.
