Eng major, just did a summer in Consulting, want to switch to IB

I am an engineering major at an ivy w/ pretty good IB placement. As a rising junior, I decided I wanted to make the switch to IB. However, I don't have any experience in finance apart from what I learned on my own. This past summer, I worked in T2 consulting, but I think I like IB better. How can I best increase my chances to land something? I understand it's rlly late in the process, but I wanted to give it a shot regardless. Also, I only have a 3.5, am I fucked? I'm p lost tbh, any guidance would be appreciated.
