Work-from-home support roles hiring this month - 3 weeks in

A company is hiring remote support agents on a rolling basis this month. I have read a lot of threads here and could not find my exact situation. 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 6 months ago, and it got easier once I kept a simple log of every call and form.
