Apart from Leetcode, what to prepare for Amazon final virtual interview for internship?

Practice coding on a whiteboard.

Medium leetcode + leadership principles (one or two examples of personal experiences for each, also identify your three strongest and three weakest)

In general amazon asks design question as well.I am not sure whether they do so for interns.

I got no LP but leetcode medium questions. Be prepared to talk a Lil bit about past experience and a couple interesting projects you have done. Chill and do your best! Internship is the most easiest way to get into Amazon

Leadership principles. Know them and be able to talk to them. Since you are an intern don’t worry about think big or frugality, but definitely be able to give an anecdote for things like disagree and commit, ownership, learn and be curious etc.

make sure to spend time on understanding leadership principles. it’s hard to come up with examples for people without prior production work experience, it’s hard even for people with work experience. but it’s half of the decision to hire, it is also common cause of failed internships.

Internship interviews are much more simpler than full time interviews. Practice coding of data structures: DFS, BFS, Trees, Tries, Hash Map, Stack, Queue, Priority Queue, Linked List. Make sure you know the complexity (both time and space) for these data structures as well as the popular sorting algorithms. Leadership princples for interns revolve around executing a task from start to finish. This would include the hardships you would face when working as a team, convincing others on choosing the method of execution, resolving conflicts and finally delivering the task meaningfully. Don't forget to enjoy the hour you have while interviewing at Amazon. It will make a difference. Good luck!

Try doing a mock interview using online coding editor and get used to it. It feels a bit different from white board coding. And also solid understanding on data structure, algorithm and cs knowledge in general are important. For me I did not do much leetcode, CTCI was enough. Good luck !

I can tell you from personal experience that during last Fall’s hiring for this summer, a LOT of people got DS/A trivia questions followed by one or two leetcode problems. I don’t know that I’ve heard of any being asked behavioral/LP related questions. Good luck.
