Pros: Compensated well, working with very talented people and well-designed systems. Nice office, lots of perks.

Cons: It wasn't a very supportive environment. It didn't really need to be, since they compensate so well. Autonomy was highly expected; positive feedback was optional. I worked an average of 49 hours a week.

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.

Pros: Great culture, work-life balance, and compensation.

Cons: There are not any I can think of.
