I applied through a recruiter. I interviewed at Two Sigma (New York, NY) in Sept 2020
Interview
Leetcode screening. 3 separate algorithm questions. 3 hours to complete, but finished in about 1.5 hours. My answers were accepted to the next round but declined to move on due to Java/Python as being the only supported languages.
Interview questions [1]
Question 1
It was 3 leetcode medium level questions, not terribly difficult
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.
