      Anonymous employee
      New York, NY
      Accepted offer
      Positive experience
      Average interview

      Application

      I applied through an employee referral. The process took 3 weeks. I interviewed at Block (New York, NY) in Jan 2015

      Interview

      I was referred by a friend. The process took about 3-4 weeks. Filled out a Hackerrank code challenge and was contacted about a week after for an interview. Had two interviews for two different teams, but for the same position. The interviews went pretty well. Had questions and my interviewers were more than happy to answer them.
