      Software Engineer Interview

      Anonymous Interview Candidate
      No offer
      Negative experience
      Average interview

      Application

      I applied through a recruiter. I interviewed at Proto (Canada)

      Interview

      Someone from the company emailed me to schedule an interview, his title was some Engineer not HR. He was in Asia so the interview was scheduled for late at night. His camera was off the entire time and asked me some tech questions. I asked what challenges they are facing at the end, he said he is not an sde engineer and don’t know the challenges. Leave me an impression of arragont.
