Got an unpaid internship with a mid-market wealth management firm, advice on what I need to do to get hired?

Hello r/financialcareers!

Like the title says, I got into this financial training workshop program that is done with the wealth management unit of a bigger financial services company. I will be learning things about finance with 50 other interns. I am a second year in college, about to be a third year after the summer

The question is, what do I have to do to get hired? I go to a University that is ranked in the top 150 by topuniversity.com, and my gpa is 3.49. I'm majoring in Applied Economics and minoring in Applied Mathematics. Eventually I want to work for a bulge-bracket bank (who doesn't?). Should I show my aptitude for working hard as well as be super friendly the people responsible for the workshop?

Any advice would be much appreciated!
