Work-from-home support roles hiring this month - 4 months and counting

I found several remote customer-support roles that do not need a degree, and I have applied to a few as a call-centre agent. 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?

Legitimate ones never ask for money up front. If they ask you to buy equipment first, walk away.
