Work-from-home support roles hiring this month - what worked for you?

I found several remote customer-support roles that do not need a degree, and I have applied to a few as a customer-service rep. 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 9 months ago, and it got easier once I kept a simple log of every call and form.
