Work-from-home support roles hiring this month after 8 years as an electrician's helper

I found several remote customer-support roles that do not need a degree, and I have applied to a few as an electrician's helper. I do not usually post, so bear with me. They use a short typing and listening test. What should I know about the test?

Ask about the schedule and what happens when call volume drops. Some roles cut hours in slow seasons.
