Remote customer-support openings I found - what worked for you?

I came across a list of work-from-home openings with paid training. This is my first time dealing with any of this. They use a short typing and listening test. Are there warning signs I should look for?

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

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