I applied through a staffing agency. The process took 1 day. I interviewed at Kelly (Denver, CO) in Jan 2016
Interview
Met an Operations Supervisor at the site. We had a sit down talk for about fifteen minutes and then we took a tour of the facility for ten minutes or so. We then sat down again and she discussed the requirements for the job, what my related experience was, and how well I get along with others. Overall half an hour. I had to call Kelly Services back that I would not be able to work for that company because there were no nearby bus stops. If Kelly would have given me the correct address from the beginning, I could have discerned that problem from the start. So I had to contact Kelly Svcs to let them know that we(myself and the company giving me an interview), had just wasted each other's time.
