Recent grad looking for financial opportunities advice!

Hello! I am an upcoming T20 university graduate majoring in Political Economy with a 3.7 cumulative GPA. While my major is not specifically in economics or finance, it is a unique hybrid that combines aspects of both politics and economics, with a focus on economics. I have a strong interest in the financial services industry, but at the moment, I have only received offers from the Big 4 audit firms. However, my aspiration is to break into the fields of Asset Management, Investment Banking, or Equity Research. It is important to note that I haven't interned in any financial-related industries; instead, my internship experiences have been in a marketing consultant start-up company and a government relations firm. I am concerned whether it is too late for me to pursue my desired career path or if I should give up on it?
