Pros: Casual work life, less stressful, free lunch, learn a lot in fast-paced environment though.

Cons: In my five years of experience found no cons...

Pros: They do not charge you for lunch.

Cons: 9-10 hour work days. Watch your back culture, witnessed middle-managers lying to upper management for personal gain. (Taking credit for others' work, throwing people under the bus -- I have been yelled at by a manager in front of upper management for not completing an assignment that I was never given). Trade room floors. Management attempts to sell this as "collaborative, with lots of communication." Trade floor rooms are LOUD. People yelling, traders trading with people over the phone. Make sure to invest in good headphones. Management seems to be apathetic to the well-being of employees.

Pros: Some desks or teams within the firm are ok.

Cons: Toxic backstabbing culture Unhappy employees and high turnover rates Old tech stack Uninteresting small projects but demanding on performance anyway Frequent restructures are confusing
