*Most undergraduate students at Caltech don't want to or intend to enter investment banking, but the ones who want to place very well.
I have never seen or heard of any caltech students working in investment banking. I know some really strong trading firms, places like DE Shaw, recruit at caltech, but I would not consider it a target school for people trying to get into IBD. I'm pretty sure the bank I work at does not actively recruit from caltech for IB.
Stanford is obviously the top target in the west coast, followed by berkeley, usc (trojan network is very strong in LA), and maybe ucla.
