Exploring Banking as Full Time option

Hi guys,

New to the forum so please go easy on me! Quick self-bio:

- Senior in Top 10 U.S college
- Just finished an internship with E&Y Consulting (Advisory) practice, have a full time offer
- First choice is consulting, but not sure I want to go back to E&Y, want to explore other options in Big 4
- Very interested in exploring banking as an option. Preferably S&T

Questions:

- Other than brushing up resume, writing great cover letters and reaching out to my school's alumnus, what should I be doing?
- My concentration IS finance, and I have A s in all my Finance classes, but I'm not confident at all to pitch a stock, or argue back against a Goldman Sachs interviewer about markets or stocks or anything, should I just read/memorize a Vault guide and read the news everyday?

Thanks for any advice!!
