I applied online. The process took 3 days. I interviewed at UPS (Salt Lake City, UT) in Sep 2015
Interview
It was first a job tour of what you can expect. Then once it was over you were asked to call then schedule a appointment if you were interested in working. Mostly they are looking for people that do some type of physical fitness everyday or every other day. They ask that because with the 1 year commitment they don't want to hire you then end up leaving the job because load is to hard. Most importantly very flexible shift.
I applied in-person. The process took 6 months. I interviewed at UPS (Lexington-Fayette, KY) in Dec 2013
Interview
I went through a series of internal tests such as loading a highly advanced area with strict time commits. They had me take an internal MAPP test that accessed if my personality was a good fit for the position. This test also accessed my quantitative skills and ability to interpret data.
