Home assignment with 3 parts:

First, 7 debugging questions in 20 minutes.

Then, 2 code questions in 70 minutes (difficult, not LeetCode questions).

Finally, 2 hours of personality tests.

If you pass that, there are 2 interviews.

Each interview is 60 minutes, where they ask you questions about how you handle situations (Amazon Leadership Principles).

After that, there is a single code question in each interview.

In an upfront interview, you're given a string like "A, _, C..." where the left side represents the "father" and the right side represents the "child" in a tree. Your task is to deserialize the tree from this string. Note that this is not a binary tree.
