      Data Engineer Interview

      29 Mar 2021
      Anonymous employee
      San Francisco, CA
      Accepted offer
      Positive experience
      Difficult interview

      Application

      I applied through a recruiter. I interviewed at Block (San Francisco, CA) in Oct 2020

      Interview

      I applied online and got the response almost immediately from the recruiter. In next 2 days I had a discussion with Hiring Manager and she was really nice and I had a great experience sharing my experience and what I am looking in the next role. Next Round : Phone Screen for SQL. This round was 1 hour long and I was able to solve all the questions. Difficulty level would be medium leetcode. Interviewer was nice and we had discussion on how to approach the problem before writing the answer. I was invited for onsite loop in next 2 days Onsite Loop (NDA signed): it consisted of 7 rounds which sounds like a lot but as the rounds kept going , my confidence level boosted and I had a great experience with one of the interviewer. from my experience Square focuses on Team Building , Cultural fit a lot. They love to understand how curious you are to fit in and adapt the new role.
