I applied online. The process took 1 day. I interviewed at Rev (Chicago, IL) in Sep 2016
Interview
The application process was fairly easy. I had to answer some multiple choice grammar and spelling questions and write a paragraph about my hometown. I was given a simple video to caption with Rev.com's software. When the company was satisfied with the way I captioned the first video, I was given two new video's to caption.
There was no interview or anyone that reached out to talk about the position. There was a test after a training video to ensure you could do the required work to a high standard.
The interview process for the freelance captioned position is fairly standard. You have to demonstrate that you can caption a video using their system. If you are able to meet metric requirements right off the bat it is not that big of a deal.
