In general, study a variety of leetcode questions with different data structures and algorithms (DP, tree traversal, stack, etc). I studied around 40 hours in total. Don't freak out if you do poorly in 1 interview as they'll look at your overall performance. Practice your interpersonal skills too as they'll want to see how you handle team interaction in the behavioral interview.

Basic Phone Interview Algorithms Personality Questions
I'll add it later, questions were 1. 2d matrix, similar to leetcode Pacific Atlantic water question, 2 were on design a data structure. I was on map and stack but you can go with recursion but i was trying to avoid recursion.
6 interviews. 5 algorithms + 1 behavioural. Topics were advanced and needed more than just the basic knowledge in algorithms but the questions themselves werent that hard. If you had a really good understanding of the topics the interviews would be easy. Got dynamic programming, trees, binary search, geometry, strings and graph theory questions
Can't say, study your data structures and algorithms.
One was something about permutations
Several problems involved knowing how to search a graph.
Code something related to DFS in language of your choice. Write out recurrence relation and runtime
