Remote customer-support openings I found - any advice?

I came across a list of work-from-home openings with paid training. This is my first time dealing with any of this. 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.

The test was a short typing check and a role-play call. Practising with a friend helped a lot.
