I applied online. The process took 1 day. I interviewed at Amazon Flex (Clearwater, FL) in Sept 2018
Interview
Conference room at a hotel. Ad was posted on Craigslist so there were lots of people applying. Mass drug tests, tax paperwork etc. Kind of chaotic. Photo was taken for an I.D. badge. Pretty much hired on the spot and if the drug test came back positive they would call and tell you sorry.
