Work-from-home support roles hiring this month - any advice?

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

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.
