Working hard among the brightest minds
Pros
Working at Citadel Securities gives you the opportunity to wear lots of hats and have responsibilities from the moment you walk through the door. It's amazing being part of a team and always being held accountable for things that directly contribute to the business as a whole. With that responsibility and accountability, you are expected to put in 100% every day, and it especially makes you work harder knowing you are making a true difference. Everyday, you work alongside the most brilliant minds. The best part is, they're also willing to teach you about a certain system or product, rather than leaving you wondering. You will constantly be challenged from a learning perspective, but also a work ethic perspective, but everyday you gain more knowledge, you get smarter both intellectually, and in terms of efficiency.
Cons
I can honestly say that I can't think of any cons... you work really hard, but it's rewarded. As long as you thrive in an environment like that, then you'll see it as a "pro."
