Breaking into IB, PE, etc from CS at a target

So I'm currently a sophmore at a target (MIT is one from what I've seen online, lmk if I'm completely off) studying CS. This applies mainly to the finance school based on my understanding though. So if I wanted to move into IB from CS what would be the main process/restrictions? I've seen some advice like taking IB related internships, and beyond that I obv plan on grinding out some of the basic knowledge that might be expected from someone in finance, and plan on continuing to study. Basically, how feasible would entering IB and related fields be? How could I boost my chances before I start sending resumes in?

Thanks for any help.
