Hi everyone! I am new to the GMAT club and am looking to gain some advice

I am planning to go back for my MBA for the Jan 2019 semester (either PT or FT depending with what school I get into). I have NOT yet taken my gmat, and am just looking to gain perspective:
GMAT: Not taken, beginning
Manhattan GMAT prep course today (8 weeks and will take at the end).
Undergrad: Small state school known as Kean University. Graduated in Finance with a 3.33 GPA
Work experience: Post college, I landed my first job (contract role) at
Bloomberg worked within Fixed Income securities. After a year, i interviewed at some firms and got an offer with
JP Morgan within their FADP program (financial analyst dev program; 2 rotations). My first rotation was within investment banking supporting Emerging Markets for Derivatives. Second rotation got placed into payment strategy.
6 months into my second rotation I got a offer from
Verizon as a Senior FP&A Analyst to join their payment strategy group. Figured i want to be closer up to the NJ/NY area as i would like to pursue my MBA eventually.
ECs: Honestly little to none, freshman year i was President for the South Asian Student Association. I worked full time hours during undergrad as a Teller/Customer Service Rep at TD for 2.5 years. I had some personal/family situations going on all at once where I had to work full time and pay for college all at once.
As I begin this new journey, I would like to know where my expectations are realistic. I would obviosuly love to attend a big school like Columbia/Wharton and am aiming to get high scores on my GMAT. Realistically-- I'd keep Rutgers in my back pocket since it's right around my house and seems more practical to attend. But i am really trying to think BIG with this whole picture.
Can anyone provide thoughts on my post? I have heard my work experience is great and I could definetly try to aim for big schools during my application process (contingent on my GMAT score). Nonetheless, trying to gain perspective from all

Thank you!!
