Stage 1: Online Assessment 1 (~60 minutes): 7 Problems involving debugging (ie you have a bubble sort written out, but is sorting in decreasing order, change it so it sorts ascending). Also ~25 reasoning problems (Riddle type questions, these are not as important as the 7 debugging, but still try to do well). The debugging is fairly simple.
Stage 2: Online Assessment 2 (~90 minutes): 2 Programming problems, easy-medium difficulty. Problem 1 was about inserting into a cylical sorted linked list (last node points to head node, ascending, 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 1). Second problem involved scheduling packages (this one was pretty hard, I can't fully remember the problem).
Stage 3: Amazon Chime interview (~45 minutes) 1 Given a denomination of coins (like 1, 5, 10, 25 in US currency), find the number of ways to represent a given amount of change.
Overall a great experience.
