I applied online. The process took 1 day. I interviewed at Adecco (Everett, WA) in Mar 2017
Interview
If you get called in for an interview/orientation you pretty much already have the job. You go in, get a rundown of the job and if you are ok with all the details of it you could sign papers and get your picture taken for a badge right there.
