Process

First, I received a HackerRank OA. I was given a technical interview a week later. If you pass it, there are 2 more technicals on one day, and then a 45-minute behavioral round. It is a pretty fast process in a LeetCode style.

Two Sigma Work Experiences

Employee-friendly; it deserves its good reputation

Software Engineer • Current Employee

October 1, 2019

Pros: A healthy, friendly working environment. Reasonable and mostly flexible hours, which is nice for people with kids. Good salaries, benefits, time off, etc. Technical challenges are good (but see further discussion in "cons"). Plenty of opportunities to switch teams within the company. A well-communicated path for career advancement.

Cons: Our business in the end is financial. So, even though we are highly technical, we are probably not going to transform the software industry the way Google has, for example.
