Great benefits, smart people but lacks culture and heavily siloed - Anonymous employee Two Sigma Employee Review

Lack of culture (which is common for a large company). Socializing does not happen organically. Most people put in their 9-5 and go home. Difficult to grow. Bureaucratic promotion process. Divisions are heavily siloed, so much that teams that work with each other on a recurring basis don’t even know the full scope of each other’s responsibilities.
