Work-from-home support roles hiring this month (Birmingham)

I came across a list of work-from-home openings with paid training. I am in Birmingham, in case local advice matters. They use a short typing and listening test. Are there warning signs I should look for?

The test was a short typing check and a role-play call. Practising with a friend helped a lot.

Keep everything in writing and save the confirmation numbers. It saved me later.
