Process
The first few rounds were okay and featured typical LeetCode problems like BFS and DFS. However, one of the rounds involved a DFS that required bitmasking to optimise runtime, which took me a while to get.

Yeah, but no
Senior Engineer • Former Employee
New York, New York, United States
January 4, 2022
Pros: Great benefits, good people to work with for the most part.
Cons: Boss was a micromanager who never liked me.
Asked multiple times per year for cross training, never got it.
Hired as a specialist in my field, then fell behind in my field because the company wouldn't make a decision on a technology strategy. Then they laid me off for cost savings and hired a contractor to replace two of us.
Never learned anything new while I was there.

Great work culture, transparent, and super talented
Software Engineer Intern • Former Employee
New York, New York, United States
October 9, 2023
Pros: Almost everyone on my team had a PhD, and everyone was really smart.
Two Sigma does a good job letting you explore around the company and learn.
I really appreciate the culture of learning and teamwork at Two Sigma.
Two Sigma focuses a lot on diversity as well.
I didn't notice any direct impact on work/experience from the CEO's feuding. Also, the work-life balance was really good (9-5).
Cons: Two Sigma has been having headcount issues recently. Also, I wish the pay progression was comparable to some of the firms in the industry.

Great company - Amazing talent
Vice President Engineering • Current Employee

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.
