I applied online. The process took 2 days. I interviewed at Two Sigma (New York, NY) in Oct 2016
Interview
One day after applying, I was sent a link to an online coding test. I was given 3 hours to complete it. The test was reasonably challenging, but I was able to answer both questions and got nearly all of the test cases correct. I was surprised when they immediately rejected me the next day.
Interview questions [1]
Question 1
Q: Finding longest subchain in a string, building unique friend circles
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.
