I applied in-person. The process took 5 days. I interviewed at Certco
Interview
Pretty simple. Fill out application, drug test, etc. I was called about a week after applying. Scheduled a one on one interview with human resources. Interview was easy, went for a drug test the same day and was hired.
I applied through a staffing agency. The process took 6 months. I interviewed at Certco (Fitchburg, WI) in May 2017
Interview
It was professionally done. With greeting, being asked questions about what I can do to where I want to be in 5 years. After finding out more about the company and hearing more about what I would be doing, it was quite clear that I was the one they were going to hire. It was somewhat quick of an interview, but was straight to the point.
