Can I get remote chat work with big outsourcing companies?

I hear that the remote work job market is brutal, but I wonder about big outsourcing companies that tend to be h|ring a lot of remote chat customer service people. I have good typing speed/accuracy, many years of freelance writing experience, excellent grammar and spelling. English first and only language. Negatives: No degree, no corporate experience. But I hear that the onboarding hinges more on testing than on resume. Is this true, or am I wasting my time looking for remote chat work?
