I applied online. The process took 3 weeks. I interviewed at Two Sigma (New York, NY) in Feb 2017
Interview
Had and online coding assessment. Then interviewed at the headquarter in New York City. The onsite interview was 3 hours in the morning with three different developers, after which I was taken to lunch. Then I was told I couldn't advance to the afternoon round. Very nice experience as a candidate overall. Nice hotel. Even got some gifts from the recruiters.

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.
