Jane Street's philosophy can be summarized in a few key principles:
We put aside ego, politics, and appearance to focus on truth. We try to admit when we are wrong, talk about our mistakes, and challenge our previous conclusions. We don't evaluate people on their education level or appearance, but rather the quality of their thinking and their contribution to our shared goals.
We know there are areas where Jane Street excels and areas that desperately need improvement; we focus on our shortcomings rather than savoring our successes.
To survive and grow amid the constant upheaval in the markets, Jane Street is committed to constant change and improvement.
Without customers or outside capital-raising, people are Jane Street's core resource. We pour our energy into hiring the best, training them to the fullest, and giving them the tools to create.
