Appeal deadline questions after an unemployment denial - 14 weeks in

I got a denial letter last week saying I left my job voluntarily, but I was let go as a call-centre agent. Any experience at all would help. I have not done a hearing before and I am nervous. If you have appealed before, what helped you prepare?

Thanks for writing this out. I went through something close to it last year, and it got easier 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.
