I applied online. The process took 2 weeks. I interviewed at UPS (Gloucester, England) in June 2015
Interview
In a tiny room for all of 15 minutes. Standard questions. It certainly felt at the time like they just needed someone, anyone as they were in need of staff and fast.
I applied in-person. The process took 1 day. I interviewed at UPS (Rochester, NY) in Oct 2011
Interview
They sat me down and asked basic questions about what my previous experience was. Then I was given a list of zip codes and areas. Then I was tested to see if I could memorize these zip codes soon after.
