I applied through a staffing agency. The process took 1 day. I interviewed at Aerotek (Kirkland, WA) in Jun 2014
Interview
The whole process was coming in to work to watch a 20 min safety video. You are given a sheet that has questions on it based on the video. After the video everyone goes through question together and you are allowed to change you answer. After that you fill out your paper work and get a date for you drug test. You have 24 hours to take the drug test.
