I received two offers, one as a Machine Learning Securities focusing mainly on options, and one as a synthetic products S&T. Goldman Sachs made it clear that it would be a role focusing a lot on machine learning. I am really interested by Machine Learning and my issue is, although I would love working with this (I've already met them), but I think I have much more to learn at Citadel (they seem more advanced on the issue). At the same time, I am affraid of the aggressive culture at Citadel (I don't want to get laid off after a few months) and I think it would be easier for me to make a whole career staying at GS on the long run than at Citadel (especially since I have probably more to add at GS). Citadel would pay more (litterally twice as much), which is not negligeable at this point, but I'd rather bet on the future than solely on present comp.
It is a bit of a difficult choice for me because I've already said yes to GS, but I'm still torned as Citadel came back to me recently.
I am not expecting a clear answer, but maybe insiders could enlighten me a bit.
