Can’t speak for two sigma but I work in a similar company. They are generally only open enough to hire people, there is a huge competitive advantage in sharing as little as possible. Lots of finance firms have a bunch of interesting problems, from scaling to security and many are getting better at treating engineers well. But usually it comes down to the fact they pay really well.
