incoming am sa at bb - advice?

hey guys,

i'll be joining a bb as an asset management sa, but i was wondering if there were any previous interns i could connect with who have similar experience? i also wanted to ask for general advice on how to prep (without knowing any logistics of the internship itself). so far, idk which product or asset class ill be focusing on, which teams ill be rotating on, and etc. especially because i'll be in a new country, i'm not really sure where to start with prep even though i've been reading a lot on factor investing so far. 

does anyone have any advice on what i can do to prepare (aside from the big ones - mastering excel, etc)? it would be really helpful!!
