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 a social media manager. I have read a lot of threads here and could not find my exact situation. Most want a quiet workspace and reliable internet. What should I know about the test?

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.
