Remote customer-support openings I found after 4 years as an operations analyst

I found several remote customer-support roles that do not need a degree, and I have applied to a few as an operations analyst. Any experience at all would help. 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 got easier once I kept a simple log of every call and form.
