Umm... This is a US-based job, right? As someone based in Europe, I find it absolutely shocking you have been requested to work ahead of your start date. This is not even eligible for asking if it's a red flag. It's insane.
edit: I see other commenters are like "well, standard practice, not necessarily that terrible". Am I living in a bubble or is it just Europe?
