I applied through a recruiter. The process took 3 weeks. I interviewed at Two Sigma in Aug 2016
Interview
They reached out to me and convinced me to consider working in finance. I agreed to interview with them. There was a simple two question online test, then a more difficult live coding interview. I had trouble getting error messages from the live coding platform. They also grilled me on knowledge of computer science basics.

Explain the algorithms for Quicksort, Mergesort, and discuss the pros and cons of either.
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.
