    Pros

    Great work environment. Amazing people.

    Cons

    A lot of changes and re-structuring of teams, but that's not necessarily a con.

    I have been working at Two Sigma full-time (More than a year)

    Pros

    Work/life balance - Management doesn't want people to burn out and actively looks out for your working conditions. My manager will regularly tell me to go home when I work past 6:30 and gives me mornings off when I work late fixing a high priority support issue.

    People/Culture - The people are great! Everyone I've worked with here has been highly competent and easy to work with. There's a huge culture of learning and exploration here. Tons of tech talks and study groups with food catered in year-round. There's also non work-related groups and competitions for just about everything like Poker, Bridge, Magic The Gathering, Basketball, Running etc..

    Work - The work itself has been quite fulfilling. I can't speak for how it is on every team, but I've worked on backend, frontend, infrastructure, networking, devops, and mobile for my team. My manager does an excellent job at matching me with projects that I'm currently interested in working on. There's a constant stream of exciting and technically challenging new ideas and features.

    Career Growth - Two Sigma wants to keep people for the long haul and it's super easy to move around the company. There's a big emphasis on setting work related goals for yourself to help you grow and revisiting them a few times a year to see where you're at.

    Cons

    There's still some red-tape around getting environmental changes approved. However, over the last year there has been a ton of progress on speeding things up and being more flexible on security concerns as more teams explore different environmental setups.

    Some of the legacy internal infrastructure is starting to show its age. There's a lot of work being done to modernize it and embrace more open source solutions, but there's still a ways to go. However, teams who are working in the cloud don't really have to worry about this.

    Pros

    Great compensation
    Pretty good benefits
    Really smart people who love to learn
    Some semblance of a work balance can be maintained

    Cons

    Really don't like the open environment. Sometimes it is very hard to concentrate
    Typical growing small company. Several people shouldn't be managers but are because they were good at other jobs

    Advice to Management

    Need to invest in more management training. Also perhaps look at system that rewards employees without them having to manage people.

    I have been working at Two Sigma full-time (More than a year)

    Pros

    The people, hands down. Experiences vary, but my two years at TS have been marked by strong collaboration and a willingness to get things done rather than marking turf. We have a lot of highly intelligent people, which opens up big possibilities for ambitious systems. The office environment is low-key and easygoing, plenty of daylight, and comfortable. The work is interesting and draws heavily from recent computer science research - in some cases implementing code based on techniques we've learned from reading published research. And you get to bring your whole self to work - not some corporate shell.

    Cons

    The open office floor plan makes it hard to concentrate at times, even with a noise canceling headset. Some highly intelligent people are really socially awkward, so you have to be really explicit about how you're feeling and what you need from them. A lot of managers need more training to manage people.

    Advice to Management

    Reconsider the open office environment to provide abundant quiet space to focus and think. Managers should be selected based on their ability to manage people well, with emotional maturity and perceptiveness. Make sure to check in with IC's to see how their manager is performing and so ICs that are new to the workforce learn how to have constructive conversations with HR and their management.

    Pros

    You will make an impact as soon as you set foot through the door.
    Everyone I work with is very smart and approachable.The company is focusing on standardizing and simplifying its platform(s) which is an amazingly exciting time to be here for those that like to be part of a redesign.
    Those that can self manage and collaborate well will have an amazing career.

    Cons

    Because everyone is so smart and able it is almost assumed that you will be attempting to reinvent the wheel to get your project off the ground but the result is a plethora of home-grown tools and services.

    Advice to Management

    Keep the culture of learning and collaboration going

    Pros

    This is a place that really cares about doing right by its employees. The perks are great and senior management is focused on the right things. There is definitely a culture of learning and a strong willingness by management to support experimentation and exploration -- feels rather unique for a finance firm.

    Cons

    Very time-consuming hiring process (on both the side of interviewers and interviewees). Not convinced it's as effective as it could be given the time investment.

    Advice to Management

    Keep it up!

    I worked at Two Sigma full-time (More than 3 years)

    Pros

    Human Resources department has been doing a great job at posting fake 5-star reviews on Glassdoor, all to convince the founding partners and the outside world that everything is just peachy.

    Cons

    Compensation is low compared to peers.
    There are no real growth opportunities. If you want to learn something new, then forget about this place and move on. The technology is arcane, bloated, poorly managed, and plain old. You will be told lies at the interview about the so-called state-of-the-art internal technology stack.
    There's no real innovation either, only pretend business-unrelated ideas which never fully materialize. Many promising projects silently fail. Most VPs and MDs are pretty bad at their job, although they are very good at blaming each other for failures, taking credit for each other's accidental achievements, exaggerating their own results, and convincing the upper management that they're worth the unreasonably high compensation.
    Partners have no idea what's going on and why things aren't working anymore, but they keep on introducing and removing dubious workflow/HR procedures, restructuring the company every 6 months, moving people around, reassigning responsibilities, and hiring external CTOs.
    Don't waste your time there!

    Advice to Management

    Dissolve your partnership and retire. You've lost control, understanding, and the very ability to properly comprehend what's going on inside your own company. It is pointless to continue further.

    I have been working at Two Sigma full-time

    Pros

    Huge emphasis on technology as a competitive edge makes it a great environment for an engineer working in finance.

    The company truly values its employees and it shows in a variety of ways. (i.e. gym, free food, professional growth opportunities).

    Work with some of the best people in the technology industry on a daily basis.

    Cons

    The company's rapid growth constantly stresses organizational processes.

    The selective interview process can be brutal.

    Advice to Management

    Try to ensure that the wonderful environment you've created is maintained as the company continues to scale.
