I applied through other source. The process took 1 day. I interviewed at Two Sigma (New York, NY) in Nov 2017
Interview
Don't recommend applying here. They have you take a 3 hr coding test on hacker rank that only verifies your ability to program competitively. Not sure if that's to give themselves an ego boost but they definitely are filtering for a certain type of technical person. The test is so narrowly focused on one particular skill it is scary to imagine what the actual environment is like.

Other Software Engineer interview reviews for Two Sigma
first interview was 60 minutes long with a leetcode hard question. second interview was 2 back to back 60 minute leetcode hard with emphasis on data structures. each interview had a 5 minute introduction and 10 minute at the end to ask questions
Standard medium difficulty hackerrank. The question involved decoded an encoded string. It was not something I had seen on LeetCode before and I think was unique to the company. The question was not that difficult but I ran out of time right before I could finish answering.
Interview questions [1]
Question 1
Decode a string encoded using a specific encoding algorithm.
It started of with one phone screen, then if you pass you have 2 back to back technicals, then 3 1 hour behaviorals, hiring committee, and management committee. Standard Leetcode and behavioral questions.
