I applied to the Amazon Jobs portal, and the day after I received an invitation to complete an Amazon Online Assessment. The first test consists of a debugging problem (very very easy if you've programmed before), second part it's 2 Leetcode questions and the third part is a workplace simulation (apply the leadership principles! i.e. the customer comes first, even before deadlines). I then received an invitation for a 2 x 45 min phone interview and was asked a few behavioral questions and a Leetcode question (easy/medium).
