Entry-level remote jobs, worth a look (Phoenix)

I came across a list of work-from-home openings with paid training. I am in Phoenix, in case local advice matters. The schedules are set in advance, including some weekends. Are there warning signs I should look for?

Thanks for writing this out. I went through something close to it 7 months ago, and it got easier once I kept a simple log of every call and form.
