I applied in-person. The process took 1 day. I interviewed at Construction Staffing Solutions (Phoenix, AZ) in Jan 2016
Interview
Filled out application, with a written Electrical theory and code test. Brief interview, then took 1 hour electrical board test. Waited for board test grade. Finished interview, went and took drug test. Came back to office to get job assignment. Not your typical staffing company, these guys definitely know how to screen electricians.
