Calling GS MD - advice?

I'd say avoid asking at the start, but it's worth a shot at the end of the call if you think it went well.

Cool. Would you ask any industry questions to show knowledge and interest?

Whenever I have one of these lined up, I look up a recent deal that the MD just closed and ask during the call if he or she can walk me through it. It shows your interest in the whole process and should endear you to the MD since you took the time to look up what he or she was doing as of late. Also, it takes up a sizable amount of time over the phone and MD's love talking about themselves and their accomplishments.

Talking about deals is a great tactic. I once sat in an MD's office for an hour in a half asking questions about a $4bn deal he just closed. But inform yourself beforehand and have good questions to ask; read the Thompson or CapIQ tearsheet, and try to look the transaction up in the news. For example, if there were multiple suitors for the deal, think about why some offers were rejected - sometimes the buyer won't have been the higher bidder, and often for stupid ego-related reasons.

That is awesome, because I've found an entire report on a deal he has recently closed. Great advice, gentlemen.

Any last minute advice?

Honestly, it seems way too early to be networking for 2013 SA positions.
