Networking Call Advice

I've got a networking call with a Vice President at a BB Bank. I have my Bachelor's and Master's in finance from a semi-target school and previously completed a summer wealth management internship at a different BB Bank, but I realized I did not want to do this. He is in equity research in Biotechnology. While I’m not specifically looking to go into equity research, I want to learn from his experience and build a connection. What types of questions should I ask during this call, and how can I position myself for a potential referral in the future?
