Pros: The firm allows the use of many different technology stacks.

Cons: Lots of old code uses decades-old technology that no one could understand right now.

Pros: Fast-paced, productive, and result-oriented environment. Interesting work: both from a finance perspective (constantly evolving trading strategies, asset classes, etc.) and a pure technology perspective (solving real scalability and resiliency problems). Technology is deeply respected and tech culture is long-term focused. Very horizontal. Everyone contributes. Thin "management layer". Little to no "face time" requirements, as long as you get your work done. Compensation is good for the industry. Free food.

Cons: - The path for growth isn't obvious due to a very horizontal structure. - "Crunch time" isn't common, but can be stressful and time-consuming. - It can be competitive.

Pros: Citadel is a fast-paced work environment that prides itself on winning and meritocracy. If you're a highly driven individual, confident in your abilities, you can make a significant impact in a short period of time. Citadel is an amazing place to create your own space. If you work hard enough on something you think is important, Citadel will likely reward you with the resources to make further improvements. Most talented co-workers I've had the pleasure of working with in my entire career. Everyone is eager and driven. Amazing Coronavirus response as well. Citadel was ahead of the curve in every respect and has put together a thorough, non-mandatory return to work plan in the late summer.

Cons: Citadel can be a tough place if you don't have the requisite skills or aren't interested in working hard. Working hard doesn't mean 80-hour weeks; it just means diligently working during the time you do put in.
