Realistic Expectations for a Junior Transfer Student With no Experience

Hello,

I am a 19-year-old former community college student transferring to UC Berkeley for Fall 2021. They have admitted me as an undergraduate Pre-Economics major, which means I cannot transfer into Haas at any point. I currently have no experience other than running my own business delivering essential goods and a part-time management position at a small business (entertainment center).

I am mostly interested in client-facing finance jobs, which is why I gravitated toward IB and PWM/PB. Until I started looking through the careers I was interested in out of graduation, I did not realize how far behind I am compared to my peers, especially being half-Asian and half-White.

I obviously plan on hustling, getting internships in Spring 2022 and Summer 2022, all while working to get the best grades possible. However, my question is: will this be enough to earn an IB or PWM/PB offer at a BB or EB out of graduation at Spring 2023?

If so, does anyone have specific advice on how I can achieve this? I am not opposed to staying a third year, though I would rather not accrue debt if possible, and location does not matter to me as long as it is in the United States. I already know which courses I need to take and that I need to network relentlessly.

If this is not possible, can anyone let me know what I could reasonably expect as a transfer student from a semi-target? 

If anybody has anything to write, I would appreciate having the chance to read it.

Thank you.
