Is this at a specific location or something? From what I can tell, NYC and Seattle just do the standard code test on your own time (and allow you to use whatever external resources you want) then if you pass that, a day of in person interviews.
Probably a specific department. From everything I've heard about Amazon, the way they treat people depends entirely on your manager. Each manager has so much leeway that every group might as well be a separate company.
Which is why you see people tell horror stories about Amazon while other people rebut them and say their experience working there was great. There's no consistency between groups.
