      Senior Full-Stack Developer Interview

      17 Dec 2019
      Anonymous interview candidate
      Vancouver, BC
      No offer
      Negative experience
      Easy interview

      Application

      I applied online. The process took 2 weeks. I interviewed at data.ai (Vancouver, BC) in Dec 2019

      Interview

      The company didn't bother to notify me about interview results, which I consider very non-professional and rude. Other than that, It was a classic, super-standard interview with whiteboard questions and some very specific react questions. Phone screening, on-site face to face interview with the hiring team - the hiring manager, lead developer and 2 other recently hired developers.

      Interview questions [4]

      Question 1

      Given a sorted, shifted array of integers, find the "breaking" point in O(logn) time. Implement the solution on whiteboard
