Working at Conde Nast HELP!

Hi I might be getting a temp admin job with Conde Nast ( I am not sure about the details, all I know is that its in the market dept, I dont know if that is within a certain mag or corporate office, someone did mention the word “corporate”) But I was wondering if anyone on this board has any advice on what to expect, basically everything, even on what to wear!
Thank you and Good Luck!
