Boutique Cold Email to Phone Call Questions.

Heres is part of an email I sent an associate of a local M&A firm near me. I was wondering what kind of questions I should ask him to come across as informed and how do I transition that conversation into an internship opportunity there?

I understand that you're a busy man, but I was hoping I could have 15 minutes of your time over the phone sometime within the next week to speak with you about your experience in the investment industry, as well as any advice you may have for someone hoping to succeed in this field. I am more than happy to accommodate whatever time works best with your schedule.
