Amazon Sortation Associate interview questions

I applied online then received and invitation to a NON PAID hiring event. We spent 2 hours completing a schedule and cheek swab drug test then took photos for our ID badges. There was no formal interview or questions beyond the applications personality test.

Answered a Craigslist Ad and applied online. Received an email 2 weeks later with a contingent offer for a Part Time Sortation Associate position. Came in with my driver's license and was told to go into one of the multiple rooms for my drug test. Entered a room with approximately 30-35 people and watched a PowerPoint presentation. We were told if we pass the drug test and background check that we would be emailed a start date and an orientation date 2 weeks before our first day of work. Received an email saying I passed my drug and background check 2 days after submitting. One week later, was told to schedule my next appointment to finish my I-9. Will update review when I have more info.
