Appeal deadline questions after an unemployment denial - 18 weeks in

I was told my separation was for misconduct, which is not what happened. I do not usually post, so bear with me. The letter lists a deadline and a hearing process, but it is hard to follow. If you have appealed before, what helped you prepare?

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

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