Two Sigma reviews

A lot of people are condescending and not helpful. Outdated tech stack with a ton of stuff built internally. This means that the skills you learn (ie working with their build system) wont translate to your next job. Impossible to work with internal mobility process. Super slow, people make it impossible to move by making you endure entire days of interviews like it's still 2016 and they have their choice of FB/GOOG/AMZN employees to choose from. At that point you might as well just look externally. They claim it's an easy process, but it is anything but. Unless you end up on the right team, there's a good chance the work wont be super interesting. General thanklessness/rudeness towards people who manage tooling and things of that like.

On the flip side, growth can sometimes be painful. - It somehow always seems like there's 20% more work to do than the amount of time there is to do it. Small teams with out-sized responsibilities in combination with the type of passionate/ambitious personality that TS seems to attract can produce an environment of intense self-imposed stress. - That same strong DIY lean? Means a lot of projects get built from 0 to 1 by one or two people, and fail to make the leap from 1 to 2 as it's realized they're a lot more difficult to make stable and production-ready than it was to produce an MVP. - As an adolescent company, TS is beginning to hit some phase changes with things like maintenance of aging software, management of organizational structure, and knowledge sharing. - Less hierarchical than many companies in its sector, but you can still feel like you're at the whims of a teetering stack of managerial decisions at times. It's often hard for bad news to propagate up the stack since people will soften what they say to higher-ups. This can lead to directional decisions being made without knowledge of the situation on the ground. - Front-end development is largely unsupported by the build/test infrastructure and varies wildly from team-to-team as each one learns separately to deal with the quirks.
