I applied through a staffing agency. The process took 1 week. I interviewed at Midwest Infinity Group (Madison, WI) in Jan 2016
Interview
Fairly easy, asked expected questions, there were quite a few people interviewing, lobby area looked worse than a dentist's office, seemed fishy, possible pyramid scheme
They essentially wanted me to start as an entry level employee, being a salesman
I had applied to a pr position, so this was an unpleasant surprise. The add was very misleading.
