Phone Discussions with Analysts

I attend a non-target and through some connections I was able to obtain a couple of names of guys who work in middle-market banks.  As they requested I sent them my resume which they are going to forward onto their HR department.  I have also set up times to have phone calls with both of them to talk about their companies and careers in investment banking.   I really want to use this oppurtunity to sound like a great canidate and have them vouch for me to their respective HR departments.   Does anyone have any good questions that should be asked, or areas of discussion I should pursue?
