I applied online. The process took 5 weeks. I interviewed at ISPA (Marietta, GA) in Sept 2014
Interview
It was a group interview of all the people on the quality control team. They all had very basic questions, some of which were behavioral. My advice to anyone applying for this position is to have real world examples of your editing and writing abilities. Honestly, their standards aren't that high since this job is an entry level position and doesn't require that much skill right off the bat. Don't sweat it too hard and you should be fine.
