S&T Informational Interview Help

Hello Everyone, This is my first post and I kindly ask for your help. So basically I have been struggling to land a summer internship. I'm a Senior at a SUNY Binghamton with a decent gpa. I've applied to basically everything and have networked with a bunch of people. Anyway, I have gotten some help from my neighbor( I coach his kids bball team). He has a friend who has been in the business for around 20 years and he passed on my resume to him. He currently works at a MM. My neighbor told me that he is "helping me out". Well the guy reached out to me and wants to schedule a phone call, he said he is willing to talk to me about the finance industry and answer any questions I may have. I know he's obviously not going to email me saying "hey kid, I got a job for you!" but at the same time I'm not too hopeful about his email. My neighbor keeps insinuating that I will receive an offer....even though we haven't even spoken yet. Why am I so doubtful? Well, non target, decent gpa, and only 2 PWM internships, which on here seem shit.

So after struggling to read that terrible post, what is your guys opinions? How should I approach this conversation? What sort of questions should I ask him on the phone interview? Should I ask to meet for coffee/lunch at the end?

Much appreciated
