Work-from-home support roles hiring this month after 9 years as a mechanic

I found several remote customer-support roles that do not need a degree, and I have applied to a few as a mechanic. 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 4 months ago, and it settled down once I kept a simple log of every call and form.
