      Application

      I applied online. I interviewed at Two Sigma (New York, NY)

      Interview

      -Applied in January, took Hackerrank OA a couple weeks later. It was pretty easy -First interview was a pair coding assessment where I had to implement a sort of binary tree class in Python and fix some functions that were incorrect. Not too difficult -Second interview was back-to-back coding questions, first one was very similar to 76. Minimum Window Substring on Leetcode, second one was similar to 3387. Maximize Amount After Two Days of Conversions -Third interview was three back-to-back behavioral interviews, majority of the questions were asking me about my resume and experience. Didn't end up getting the final offer
