      Software Engineer Interview

      Neutral experience
      Difficult interview

      Application

      I interviewed at Two Sigma (New York, NY)

      Interview

      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.

      Question 1

      Decode a string encoded using a specific encoding algorithm.
