Upcoming chat with an MD

Hello,

I reached out to an IB MD on linkedin asking for the opportunity to talk with him about his career as I am interested in building a career in Investment banking. We have a brief call scheduled on Monday Dec 2 and he said that after we talk he’d circle back around after my semester ends in 2 weeks. I have some general questions for him, but do not want to waste his time. What are great questions that aren’t obvious? As well as what are some things I should prepare to possibly be asked? I am wrapping up my first semester in a MS Finance program and come from a non Finance back ground. My background includes helping build 2 businesses from scratch.

Thanks.
