Pros: Coworkers work very hard and are very smart. This may be a con if you want to get ahead or coast somewhere, as this is not that place.

Cons: Politics at many levels; promotions/leveling seem arbitrary. Various senior hires made that get paid 2x or 4x what people who started out of college and have been working a few years make. These senior hires do not contribute 2x or 4x the value.

Pros: Smart people, lots to learn.

Cons: Non-zero pressure, though not too bad.

Pros: - Intelligent and humble coworkers - Great pay - Engineers are promoted and paid based on merit. There is transparency regarding levels (junior, senior status, etc.), and your guess is likely correct about where others are. - With everything in technology and trading constantly changing, there is much room for growth and taking on new responsibilities, even immediately after starting. - Everything is solid, including culture in general, 401k, massages, breakfast, lunch, snacks, five weeks of vacation shortly after starting (which everyone actually takes), and yearly company trips. - Useless meetings are cut short or cut out; there is little opportunity for being bored. - Team leads aren’t simply middle managers; they’ve excelled at the role they are leading. - Expectations are extremely consistent: focus on clean, simple solutions, own the stack, and grasp the feedback loop of development.

Cons: - Making significant changes that affect trading can be stressful, though this is largely mitigated by frequent releases and having a plan if your solution is broken.
