      Software Engineer Interview

      16 Jul 2017
      Anonymous employee
      Ottawa, ON
      Accepted offer
      Positive experience
      Easy interview

      Application

      I applied through an employee referral. I interviewed at Ciena (Ottawa, ON) in Nov 2013

      Interview

      I was contacted by a recruiting agent by telephone initially. An interview was scheduled that ended being about two-and-ahalf hours in length. I was greeted very professionally by my manager (to-be) and he was the first person to interview me. He basically went over my resume and experience and did not test me on a lot of technical questions and there were no programming quizzes, in fact that was the theme throughout the interview. Thereafter, my manager left and I was interviewed by two pairs of people in succession; one pair consisted of two Principal (i.e. level-4) Software Engineers both belonging to my immediate team and the second pair was also a level-4 Software Engineer along with a different manager. Thereafter, my manager returned to finish up the interview and discussed some of the products that the team worked on. I was then invited to be interviewed with the Director on another day. That ended the interview process
