It used to be a great place to work - werkgeversreview Anonymous bij Two Sigma

The cons certainly outweigh the pros. There are many issues that stem from the top. It's no secret that the co-founders are in a feud and simply can't make decisions. This cascades down the entire organization. Two Sigma has been stagnant over the last 5 years due to this issue. They've lost some really talented people and have also had multiple layoff rounds due to poor fund performance. TS used to be a really great place to work but has drastically fallen from grace due to immaturity across the organization and at the highest levels of management.
