I applied online. The process took 1 day. I interviewed at Kelly (South Milwaukee, WI) in Dec 2011
Interview
I filled out an online application and was called a fee days later. I was given a brief description of the job and the details of the schedule and was asked if still interested. I then had set up an interview for the next day where they asked a few questions about tech support scenarios and how I would handle calls. Very non technical questions. I was then offered a position and was given more information on the job.
