I have my Amazon Day 1 (AD1) coming up for a new Area Manager role and was wondering what people recommend wearing.
Is there an actual dress code for AD1? Would business casual (polo/button-down + khakis/jeans) be the safest option, or is it more casual than that?
Also, for anyone who has attended recently, is there anything you wish you had known beforehand about what to wear or bring?
Thanks!
