Undergrad looking to get into credit or market risk

Hi all,

Long time lurker, decided to finally make my first post to ask for a bit of advice. I'm currently a junior at a non-target university in Boston studying econ and stats. I really enjoy statistics and want to go to a masters program in stats, but am not a strong candidate now because of my low GPA.

I'm working for the summer at a Big 4 in risk analytics, but was thinking about going for credit or market risk positions for full time. Can anybody shed any light on how stats/math related working in risk at a bank is and if working at a bank would improve my candidacy for grad school even if it's not in IB? Is it hard to break into risk from Big 4?

Thanks
