Pros: Wonderful collaborative culture, full of smart and interesting people.

Cons: It can be difficult to find a role or project where one can make a significant impact.

Pros: I enjoyed it a lot and it was a good environment.

Cons: Too stressful at times, but expected.

Pros: - Laid-back, non-corporate atmosphere with very little hierarchy. - Great colleagues, competent at their jobs, happy to collaborate, and overall nice people. - High autonomy in your day-to-day work; you structure your day/week yourself and periodically check in with your manager to ensure priorities are aligned. - Taking on responsibility early is welcomed. - Communication with your clients (the traders) is extremely easy and direct. Traders generally have a good understanding of the constraints developers work in. - Frequent cross-office collaboration; this of course depends on your projects, but shared projects are common. - Extensive training and continuous learning programs, both by internal and external trainers. - Very little internal competition. - Very little red tape; knowledge and code are freely shared between teams. - Very little process in the way of getting things done; usually, you can just "go ahead and do it." - Feedback and suggestions are always welcome regardless of your position or seniority within the company. - Wild annual company trip with fun events in great locations.

Cons: - Lack of hierarchy sometimes leads to ad-hoc organization and unclear ownership. - General "go ahead and do it" can take some getting used to if you are used to more formal processes. - The amount of responsibilities can sometimes be quite high. - The company is in growth mode, which has led to relatively few experienced developers left in the company.
