Appeal deadline questions after an unemployment denial

I got a denial letter last week saying I left my job voluntarily, but I was let go as a software tester. It has been a long 25 weeks. The letter lists a deadline and a hearing process, but it is hard to follow. Did you bring documents or only talk?

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

Stay calm and stick to facts. Mine lasted about thirty minutes and felt more like a conversation than a trial.
