Pros
I work for Cubist (Point72's quant arm). I joined the company as a junior research analyst after getting my Ph.D. - People here are extremely helpful and talented. You would get help whenever you need it, from your manager, mentor, colleague, and even the CEO, which is especially important to a junior person like me. - You got chances to do interesting projects that are at the core of the trading business. If you love finance research, this is the place to go - the environment is similar to academia; plus, you can see the real impact of your research. - Employee benefits are awesome. You get free insurance for the family - medical, dental, and vision.
Cons
To be honest, I have nothing to complain about. It has been 1.5 years, and never have I regretted my decision since I joined the firm.
