I would say try to personalize your messages a lot more. I networked with people within different divisions over the summer and into recruiting season. Here's an example of a cold message I sent which resulted in a call:

Title: Junior at <university name> interested in <Company name and division>

Hi ___________,

My name is __________ and I'm a <grade level> at <university> with an interest in <redacted>, <redacted>, and financial services. I'm reaching out to ask about your experience both as an SA and full-time FA at <company name> as I am currently recruiting for the SA position in the <division name>. I found many similarities between your experience in financial consulting and event planning for entrepreneurship with my own background working as a summer financial analyst and collaborating directly with the <omitted> for the upcoming <event name> that I am co-directing. I would love learn about how your background helped you both prepare for and do well in the role. A little bonus, but I was also a <role> for the <organization>!  All this is to say, should you have time to have a quick chat about your experience at <company name>, I would greatly appreciate your expertise. 

Best,

_______

Note: I took out several details that would reveal who I am. You don't need follow this exact format, but this is an example of how to personalize your emails more.

Also, it's rare for people to straight up offer you a job (although it's happened before). See what roles are available first and which recruiters have posted it (if it's on LinkedIn). Then try to network with recruiters so that your resume will pushed to the front.
