Summer 2022 Bank Internship Referral

I'm at Deloitte as a financial advisory Consultant and quantative analyst intern. I'm a third year in mathematics and statistics. I also am a mathematics teaching assistant at my university and they typically only make students 4th year+ TA's. I really want to transfer into a bank and work there as an intern. I saw a bunch of summer 2022 internships at JP Morgan, Citibank or any of those. I'd appreciate any help. Edit: I honestly don't mind where it is, I just want to diversify my Internship experience. #citibank #rbccapitalmarkets #jpmorgan #jpmorganchase #goldmansachs #bloomberg #finance #investment
