Breaking into IB as a graduate student from a top-2 CS program?

Hi guys,

I graduated from a top-25 university/top-2 public university (big target school for IB) with a liberal arts degree and I am currently a masters student in a top-2 CS program (which also has a top-20 business school). I was wondering what kind of "skills" I need to show to break into IB given my background? I know this is a really broad and open ended question but I have noone else to turn to and am looking for some insight.

EDIT: I graduate August 2016 so I'm looking to apply when the recrutiing cycle opens up later this year. This summer I am committed to doing an internship through my program so i can't really do anything else.

I guess I am wondering how I can use the top-20 business school I have at my disposal to leverage the skills I need to show to even have a shot at getting an interview at banks next fall. Maybe some certifications? Any help?
