Technical Screening for Microsoft SWE II United States. Be honest with me is Leet code 75 + System design enough to pass?

As the title says I have a screening for Microsoft SWE II. I know it's going to be a data structures and algorithms interview. I just want to know what kind of difficulty I should expect. Like will the problems be more hard or more medium? Will the problems be single topic problems like graphs, binary tree, linked list or will they be problems that require several techniques mixed into one solution? Long story short, please, anyone who has managed to pass this interview(or any interview from a company of similar size) give me some advice.
