There was no actual interview. You played 3 "games" on the application to determine if you are a good fit for Amazon. The "games" were: Tetris, putting products on the correct shelves, and filling an order bag. If you did well on the "games," then you were allowed to choose your start date and preferred shift.
I applied online. The process took 2 months. I interviewed at Amazon (Chino, CA) in Oct 2017
Interview
The interview was very informal, and was pretty much a group orientation. There was no one on one process, only group presentation and drug test. The dress for this event is extremely casual.
I applied online. The process took 1 week. I interviewed at Amazon (Lenexa, KS) in Sep 2018
Interview
It was a 20 minute online test that anyone with a high school education could pass. After that was a simple orientation presentation and drug test. A few days later were two days of training. Very simple.
