It was a drive in a campus for Amazon pay team. Was really exhausting, I was only called for two interviews but had to just sit there and wait for hours before each. Took all day, and they didn't even hire anyone from the drive. First interviewer was cool, seemed like a genuine guy. Second interviewer, younger than the first, was totally faking his smile, seemed egoistical, started interview with "what is you favourite data structure", implying he would ask hardest question from that and ridicule you, I first answered Hash map, he told me to choose something else, I then chose Tree, he asked 3 algo questions on Tree and time complexity of solutions, which I answered correctly, and he then switched to another misc algo question about sorting a topologically sorted linked list with both positive and negative numbers
