Entry-level remote jobs, worth a look - any advice?

I came across a list of work-from-home openings with paid training. I am in Fresno, in case local advice matters. They use a short typing and listening test. 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.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
