Remote customer-support openings I found - any advice?

I came across a list of work-from-home openings with paid training. I do not usually post, so bear with me. The schedules are set in advance, including some weekends. Are there warning signs I should look for?

Ask about the schedule and what happens when call volume drops. Some roles cut hours in slow seasons.

Read reviews from current staff on job-review sites before you accept.
