I applied in-person. The process took 3 days. I interviewed at Concentrix (Atlanta, GA) in Mar 2015
Interview
The interview consist of general computer testing. i.e typing, computer verbiage, knowledge of navigation, etc.
The ad I saw was on craigslist for a job fair. Lots of people came and alot got the job. They hire in masses but its also a high turn around rate because of Payroll issues.
