      Waterloo, ON
      Accepted offer
      Positive experience
      Easy interview

      Application

      I applied through university. The process took 1 day. I interviewed at IBM (Waterloo, ON) in Sept 2014

      Interview

      There was a general meeting with everyone prior to the individual interview. One on one, lasted for 45 minutes. Asked generally about my resume, projects I've worked on, what I wanted to get from all this, general interview questions. Then this is followed by some technical questions. At the end was told about what IBM does and given chance to ask questions. Very casual overall.
