      IOS Engineer Interview

      Positive experience
      Average interview

      Application

      I applied through a recruiter. I interviewed at X-Team in Jan 2020

      Interview

      The interview process took me across 4 different phases. Phase 1 consists of a behavioral interview with a few moderate technical questions. Phase 2 is more about the client you could be working with and whether you feel comfortable with them. This phase was pretty similar to Phase 1 but without the technicalities. Phase 3 involved a more technical interview with one of the tech leads for the client I was being considered. Phase 4, the final one for me, was a mixture of the previous three phases, but this time with the client. Overall, the process is the usual; they try to validate your skills and aptitude before presenting you to the client.
