It's bound to happen one of these times, right?  I keep getting closer.  The first time I applied, I was in college, didn't have much to show and they were very polite, but i'm sure they laughed when I left the room.  The second time I applied was for the After Effects position.  Though I was recommended by the person they were going to hire, someone else was hired before I even got my portfolio in.  With the Layout Artist, Pixar actually called me up and flew me out for an interview.  That was amazing.  Thought they didn't offer me a job, I was that much closer.  Now, I'm gearing up for round  four !  Wish me luck.
