Tips for Networking Call with MD

Hi, I'm a college sophomore at a target university looking to break into IB in 2021. Recently, I was lucky enough to schedule a networking call with an MD at one of the top-tier firms. I understand how important this can be in the outcome of my recruiting efforts, so I'm asking for any tips/recommendations on how to leave a good impression with the MD from those of you who have gone through this process. What are some thoughtful questions I can ask? How can I prepare beforehand? Should I make this call lean towards a more casual vibe, or should I stick to professional questions? These are some of the core questions I have, but overall I just wanted some insider info on what people at that level value in a candidate, and how to make the most out of this opportunity.

Thanks!
