      Pros

      With respect to the technicality of the work, it is very stimulating.

      Cons

      The people working here have astronomical potential to start their own businesses, they should rate themselves more.

      Culture & bureaucracy hurting progress & growth

      11 May 2021 - Systems Engineer 
      Recommend
      CEO Approval
      Business Outlook

      Pros

      People are generally nice, very polite with one another. Benefits are quite generous

      Cons

      There's a lot of internal politics. Hard work doesn't pay off. There's a lot of internal maneuver you need to manage in order to be "successful". It is extremely difficult to grow or learn new things, as a lot of the time is dedicated to resolve internal bureaucratic issues

      Decent For a Finance Company, But There Are Better Jobs For Engineers Elsewhere

      25 Mar 2021 - Software Engineer in New York, NY

      Business Outlook

      Pros

      There are some very intelligent people here that you can learn a lot from. The benefits are pretty good, but the base salaries leave something to be desired.

      Cons

      A lot of people are condescending and not helpful. Outdated tech stack with a ton of stuff built internally. This means that the skills you learn (ie working with their build system) wont translate to your next job. Impossible to work with internal mobility process. Super slow, people make it impossible to move by making you endure entire days of interviews like it's still 2016 and they have their choice of FB/GOOG/AMZN employees to choose from. At that point you might as well just look externally. They claim it's an easy process, but it is anything but. Unless you end up on the right team, there's a good chance the work wont be super interesting. General thanklessness/rudeness towards people who manage tooling and things of that like.

      Great, Relaxed Company

      CEO Approval
      Business Outlook

      Pros

      * Solid pay (lower among its ilk) * Good work life balance * Good people skill development

      Cons

      * Pay is lower than many peers * Senior management is hired externally rather than promoted internally * Much of the employee expansion is sub-optimally planned and has been put to work on tools and products that don't end up moving the needle

      A top tier place to work

      1 Feb 2021 - Data Scientist in New York, NY
      Recommend
      CEO Approval
      Business Outlook

      Pros

      - Hours are very fair especially for financial services industry - Smart and conscientious coworkers who want to help you succeed - Data science pro: quants are front and center in the business model, their work directly drives investment decisions

      Cons

      - Intellectual property constraints limit exposure to other smart people you could otherwise learn and grow from - Recent "gains" in diversity are small and inconsistent across divisions - Lack of structure when it comes to people management- probably works great sometimes but I have found it challenging.
