Work-from-home support roles hiring this month after 4 years as a customer-service rep

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. It has been a long 22 weeks. Most want a quiet workspace and reliable internet. 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.
