Work-from-home support roles hiring this month - what worked for you?

A company is hiring remote support agents on a rolling basis this month. I would rather hear the honest version than the polite one. The schedules are set in advance, including some weekends. What should I know about the test?

Thanks for writing this out. I went through something close to it 8 months ago, and it settled down once I kept a simple log of every call and form.
