Why so fixated on banking jobs mate? It ain't all the glamourous as what the industry makes it out to be.

To be honest, you are requesting help from people here, to see if there are any other ways you could enter your dream job. But you're not revealing your qualifications. We don't even know which uni you're from, and what degree you have (can only assume its related to Comp Sci). It makes alot of diff if you're from Ivy leagues, local U, or long dist learning. Also makes alot of diff if you're Summa/FCH, or others.
