Pros: Work-life balance can be good, at least sometimes. The office location is great. Free drinks and company trips are offered. Compensation can be good when the market favors it.

Cons: If you are a graduate and interested in market making, this can be a good firm for you to learn. Technologies used are very limited, not fantastic. After some years, you can decide if you're really interested in this area and probably you can still find another job in the market (although the skills may not be that marketable). Some senior folks are not that friendly and make you feel terrible. For example, they may be talking something completely wrong without knowing it, and they stop you to challenge it. How would you feel if your 'manager' is like a kid that doesn't know the programming basics? Besides this, insulting words and personal attacks are something you may experience during work.

Pros: Smart teammates who want you to succeed. Interesting project that provides real and obvious value to the team. Focus on providing immediate value with short feedback loops and frequent code review. Amazing baristas.

Cons: For interns, the provided housing wasn't great, mostly because it's in an old building.

Pros: * There are smart people. * There are interesting technical challenges. * The company is making money and increasing its market share. * Some people manage to have a semblance of work-life balance.

Cons: * There is a lot of politics and internal competition. * Management sometimes enables hostile behavior from senior/valuable employees, and there are certain people who are known for being... unpleasant. * High pressure and long hours are commonplace.
