The short answer is "it doesn't work." I haven't made a trip through there since I was in my early 20s and feel very lucky by that. My only experience with them is that they deliberately make it as difficult as possible and intentionally add as much shame and abuse as they can get away with.
A lot of it depends on what state you live in what the rules are and how much you get per week. Some base rules are set by the Fed. Where I'm at, the top benefit have been about $340 a week, but its technically based on your salary while working. During this time you have to apply for a certain number of jobs and provide documentation that you're doing so. The thing that I found difficult with them is that if your documentation wasn't complete in any way: you forgot to sign something, or put the proper date on it, or your potential employer didn't mail in the card they were supposed to, they docked you that week's benefits, but counted it against you for the total number of weeks you are eligible. I never did manage to get a check out of them. Most people I know give up after a couple of months trying to get a check. If I lost my job, I don't think I'd even bother with it., tbh. You're better off using that time working on getting a job, which is probably their intent.
Of course, all of this may be outdated with the program established recently for Covid-19.
