Coffee chat with ED

Hey everyone,

I have a coffee chat coming up (from cold emailing) with an ED (Commodities Sales at a BB).

--> What to expect compared to coffee chats that I am more used to with An-Asso-Vp ?

--> What questions are relevant to the role of D/ED in S&T in general but also more particularly in Commodities

--> Guy has an important background in physical commodities, what type of interesting questions could I ask / what kind of support can I use to research the commodities he is specializing in

--> Should I mention more down-to-earth subjects (internship openings/referrals...) or avoid them for this chat

Thank you in advance !
