Round 1: A 6-10 person Zoom cattle call where you are only spoken to -- no questions are asked
They are looking to hire 60-100 people!!! But they're "interviewing" (looking at) 600-1000 to begin with.
Round 2: If they like your looks, you are invited to another Zoom call. The next day at 8am. Presumably you get to talk to them at that call, but that's just a guess didn't say. If you're invited to stay on for Round 3 at 9am, that means the "job" (not explained what it is) is yours.
