Remote customer-support openings I found - 14 months and counting

I came across a list of work-from-home openings with paid training. This is my first time dealing with any of this. The schedules are set in advance, including some weekends. What should I know about the test?

Thanks for writing this out. I went through something close to it 14 months ago, and it settled down once I kept a simple log of every call and form.
